Hyunwoo entered the yard and saw Hoseok's car parked in the garage. "I thought he still outstation," he mumbles to himself as he parked his car, next to Hoseok's car - where Kihyun's usually parked his car. Honestly, Hyunwoo dislikes the empty space in the garage. Not having his wife's car parked there, for some reason, make him feel incomplete. He wanted to repair Kihyun's car, which crashed during the collision, but the car cannot be fixed at all. He has plans to order the exact same model, but his rationality stopped him from doing so. He cannot help but think that the collision will leave Kihyun with trauma, and there is no way Kihyun would want to drive the same-looking car. In the worst possible scenario, Kihyun probably refuses to drive at all, just like he has been avoiding swimming ever since the cruise incident.

Hyunwoo entered the house and wanted to greet the caretaker and Hoseok loudly, but he didn't when he sees them standing in front of Kihyun's room - as if they are eavesdropping on what is happening inside. As he approaches them, he notices Insung is squatting in between the two. "Insung is here?" he asked himself. Then, something clicked in his mind. "Hyungwon-ie?" he approaches them in a rush. "Is Hyungwon inside?" he asked no one in specific and making the other three look at him in surprise.

"Chief Sohn, why are you home at this hour?" the caretaker asked.

"I was rushing this morning," Hyunwoo simply answered. He didn't tell them exactly that he comes home because he feels guilty for leaving without seeing his wife. He is pretty sure Kihyun wonder where he go without their routine morning greeting. "When did you come back from your outstation?" he asked, ignoring Hoseok's judging eyes.

"Just now," Hoseok answered.

"Chief Sohn, I am sorry. I only left for a moment. When I come back, Dr. Chae already locked the door. The brain monitor is quiet. It means everything is okay, right?" Insung said, worried.

Hyunwoo smiles. "Of course, it is okay. Dr. Chae would never hurt Lawyer Yoo" he gives reassurance to the young man. He looks at the door for a moment, "Hyungwon might switch the monitor off," he mumbles. He pulls out a pen from his pocket and uses it to open the locked door.

"Are you serious right now?" Hoseok asked, "You two have been married for years, and you still don't have his key room?" he face-palming himself.

"Do you?" Hyunwoo simply replied.

"I return it to him after you guys get married," Hoseok answered, honestly.

"You should just give it to me," Hyunwoo proceeded to unlock the door with the pen. "Kihyun teaches me this trick. I never thought I would actually use it," he added.

"He teaches me too" Hoseok leaned to the wall, "A part of me was worried he might take after his client's bad practices, but these are indeed useful tricks in an emergency"

"I've seen Lawyer Yoo do this. He does it so fast," Insung stated.

"You can't compare us to him, Insung-ah. He is trained by a professional. We are trained by an amateur," Hyunwoo and Hoseok replied simultaneously.

"Why didn't you use the same room with your wife?" the caretaker asked out of curiosity.

Hoseok laughed a little. So, does Hyunwoo. This topic has been an issue of confusion for years now.

"Well, before I am his husband... I am just his tenant. We got married so suddenly and were still getting used to each other presence back then. Then, it just becomes a habit. Plus, there is some time before the tenancy contract ended" Hyunwoo smiles proudly when he manages to unlock the door.

"Are you saying you are still paying rent?" the caretaker is confused.

Hoseok chuckles as Hyunwoo is taken aback by the question.

"That's not what I mean," Hyunwoo replied before he carefully twisted the doorknob and slowly opened the door. He takes a peek inside and sees Hyungwon staring at the sleeping Kihyun, and just like he predicted - the brain monitor is switched off. He knocks on the door, and the psychiatrist turns to look at him. His heartbreak a little when he sees Hyungwon in tears. "Is it okay if I come in?" he asked.

Hyungwon nodded as he wipes his tears. "Why are you here at this hour?"

Hyunwoo entered the room, pulling Hoseok to come with him. He mouthed 'It's okay' to the caretaker and Insung, before closing the door.

"You are here too?" Hyungwon asked when he sees Hoseok.

"Yeah," Hoseok goes to sit on the bed, near Hyungwon. Checking the latter condition, Hyungwon looks tired and sad.

Hyunwoo climbs the bed, whispering his greeting to Kihyun before stealing a quick kiss from his wife's lip. "Did you two 'talk' a lot?" he asked as he fixes the blanket over his wife's body.

Hyungwon did not answer; he appears to be lost in his thought.

"Are you okay?" Hoseok asked as he is reaching out to hold Hyungwon's hand.

Hyungwon takes a deep breath, "Can I see the collision video?" he asked instead.

Hoseok looks at Hyunwoo, and Hyunwoo just nodded.

"I think I have it in my email," Hoseok said as he searches for it on his phone. When he found it, he plays it for Hyungwon. "Why do you want to see this?" he asked after the video ended. He notices Hyungwon flinching while watching the video.

"Just to check something," Hyungwon answered before he excuses himself to use the bathroom. Something about the video brings back memories he has forgotten, and he needs some time alone to get himself together.

"Do you think he takes a look at Kihyun's Pandora box?" Hyunwoo whispered.

"But, isn't his pandora box technique required him to talk to the other person? Can Kihyun respond to his suggestion, though?" Hoseok replied. "I have read a few clairsentient articles, and there is this one article talking about emotional tracking ability. It says that a high manifestation clairsentient may be able to perform emotional tracking by putting themselves in the other person's mind. It requires a huge amount of focus and energy."

"Do you think Hyungwon did that? He looks exhausted."

"His body is still adapting to his new heart. It's hard to tell," Hoseok sighed. "But I hope he didn't. It is dangerous because it may cause him to lose his self-foundation."

Hyunwoo and Hoseok stop talking when Hyungwon comes out from the washroom. However, both Hyunwoo and Hoseok are caught off guard when Hyungwon suddenly fainted before he can reach them.

******************************

"What happened?" Minhyuk asked as soon as he reaches Hyungwon's side.

"He is just exhausted. Sunho has checked on him. Everything is fine," Hyunwoo answered.

Minhyuk turns to look at Hyunwoo and notices Hoseok standing next to him. "When did you come?"

"Guys," they are all looking at the voice. It's Changkyun and Jooheon.

"Is he okay?" Changkyun asked worriedly as he takes a look at Hyungwon.

"Yeah, just tired," Hyunwoo answered as he smiles a little at Jooheon.

"What was he doing? How can he faint from exhaustion?" Changkyun refuses to solely take what he was told; he needed more explanation. Then, he notices Hoseok.

"I come home this morning," Hoseok said before the Neurosurgeon can ask him the exact same question Minhyuk asked him earlier.

"Changkyun is right. He doesn't even leave his own room. How can he get this exhausted?" Minhyuk said.

"Where is Insung?" Jooheon asked.

"Apparently... " Hoseok clears his throat, "He left home this morning. Insung told me that Hyungwon visited Dr. Jee in prison. Then, he comes to see Kihyun. He passed out in Kihyun's room, and we were there when that happened."

"You go home? Why?" Changkyun wondered if something happened to Kihyun.

"Just to see my wife," Hyunwoo simply answered. "Insung is still at home," he added.

"He passed out in Kihyun's room? Do you think it's because of the sensation he picks up?" Jooheon asked.

"Hey," Minhyuk holds the psychiatrist's hand as the latter is waking up, "You are making us worried."

Hyungwon look around, "ER?" he whispered.

"Yeah, you fainted from exhaustion," Minhyuk answered as he helps Hyungwon to sit up. "What were you doing, Won-ie?" he asked worriedly.

Hyungwon wasn't paying attention to Minhyuk, though. His focus is fully on Changkyun; he stares at the Neuro, looking at every inch of his face. "Now, I know why I have such a soft spot for you. You really grow up well," he blurts out.

Changkyun frowned.

"Is he hallucinating?" Jooheon whispered to Hyunwoo and receives a head shakes.

"Daniel is not just an alias, Changkyun-ah. That was your name," Hyungwon said.

"I don't think I have changed my name," Changkyun replied, not sure what to do in this situation.

"You don't remember it too. None of us remembers those memories," Hyungwon sighed. "But, he does. He remembers everything until the cruise explosion jumbled up his mind."

"Are you talking about, Kihyun?" Changkyun is really confused.

"You said there is a possibility he becomes like this because the collision reminds him of the explosion. I tracked his emotional history. It does have something to do with the cruise, but not the explosion."

"What do you see, Hyungwon?" Hyunwoo asked.

"There is something I need to tell you and Changkyun first" Hyungwon wonder how he should tell them about what he found out during the emotional tracking.

"Is it about my sister?" Changkyun asked.

"Dasom wasn't pregnant. She had cancer," Hyungwon said.

Both Changkyun and Hyunwoo wonder if they heard that right.

"Two days before the cruise, she takes a medical check-up. She receives the result while on the trip, right before the explosion. She wasn't hurt during the explosion; she gave up swimming because of cancer," Hyungwon added. "I am so sorry."

"So, that's why the pregnancy test was always resulting in a false positive. The cancer is messing up with her hormone," Hyunwoo mumbles.

Changkyun suddenly left. Jooheon wanted to chase after him. But, Hyunwoo stopped him.

"I will go," Hyunwoo said as he patted Jooheon's shoulder before chasing after Changkyun.

****************************

"Changkyun-ah" Hyunwoo parked his car recklessly, as he rushes to chase after Changkyun.

Changkyun ignored Hyunwoo completely as he heads to his home and straight away to his working room. He reaches out for the box on top of the bookshelves, he opens the box and pulls out a white envelope. He tears it off and pulls out the document from it. He quietly goes through it, and the content makes his leg goes weak.

When Hyunwoo reaches the room, he sees Changkyun falling down and rushes to catch him. "Hey, it's okay. I am here with you," he said as he hugs Changkyun tightly. A little taken aback when the latter burst into crying. "It's okay, Changkyun-ah. I am here," he whispered to calm the latter down.

"Hyungwon is right," Changkyun releases himself after he feels a bit calmer. He shows the paper to Hyunwoo. "She gave up without confirming her condition," he said while sobbing.

Hyunwoo takes the paper from Changkyun's hand and reads it.

Please come for a further check-up.
Your test indicates that you have stage four ovarian cancer.
We need to perform more test to confirm the result

"When did you get this?" Hyunwoo asked. The doctor's note makes his brain goes blank. Stage four ovarian cancer? It's either he didn't pay enough attention to his late wife, or Dasom is hiding her symptoms from him.

"A few days after the explosion. I was so lost at that time, so I don't really pay attention to it," Changkyun wipes his tears, trying to stop crying - but failed.

Hyunwoo watches Changkyun's reaction closely; he starts tearing too. He pulled Changkyun into a hug again, "Our Changkyun-ie, you are still waiting for her," he whispered. His heart ached so much when Changkyun nodded while crying hard - face buried in his chest.

Later that night...

Jooheon takes a peek at his shared bedroom with Changkyun - Changkyun is sleeping, cuddling Hyunwoo. He smiles when Hyunwoo notices his presence before closing the door again and going to the kitchen. As he is brewing some coffee, Hyunwoo shows up behind him.

"Where are the kids?" Hyunwoo asked as he looks around.

"I sent Harriet and Henry to your house. Hoseok already picked up the triplet and Sang Wook from school too. Guess, for tonight... the kids are sleeping over at your place."

"That's better. Henry and Harriet are old enough to understand everything. They will be upset if they look at their Dada like this," Hyunwoo said while nodding, "How is Hyungwon?"

"Minhyuk takes him home," Jooheon answered. "Is he okay?"

Hyunwoo sighed heavily. "After all these years... he still waiting for her, Jooheon. He is still hoping for her to return home."

Jooheon instantly gets upset. "He can never let her go, doesn't he? I want him to have some sort of closure, but I don't know what I should do," he exhales heavily.

"I want to see Hyungwon."

Both Hyunwoo and Jooheon turn to look around.

"Hyungwon said there is something I have forgotten. I want to remember what it is."

"Are you sure?" Jooheon asked.

"I've been thinking about it, and I realized I have no memories of my childhood. Except that, I was lost."

"Many people don't remember their childhood well, Changkyun," Hyunwoo said.

"You heard what he said.  Neither Hyungwon nor I remember about it, but Kihyun does. Chae Hyungwon never lies. He hides some facts from us like who he really is, but he never lies."

Jooheon and Hyunwoo look at each other.

"Okay, okay," Hyunwoo said as he walks to Changkyun. "We will go to see Hyungwon, okay?" he said as he cupped the Neuro's face. "Let's change your clothes before we go, okay?" he takes Changkyun back to the room.

Jooheon sighed as he pulls out his phone. He gives Minhyuk a phone call to let him know that they are coming.
