Taemin saw Krystal coming alone from the cafeteria. From the morning he couldn't get a chance to talk with her alone so he went near her. She doesn't look in a good mood; sadness has occupied her face completely.   "Are you okay?" Taemin asked her after he stood before her. Krystal looked at him; "Kai told me everything" he said and smiled at her. Krystal simply nodded her head and tries to be calm and strong before him. Taemin got a small smile seeing her being strong, "Everything will be fine" Krystal nodded without looking at him.   "If Kim Samcheon says that he will look after everything, I'm sure he will do it, don't worry," he said. Krystal again nodded without looking at him. "Only Samcheon can convince Imo, so he will do his best," he said.   Krystal looked at him, "I'm fine Taemin-ah" she replied. Taemin nodded and moved away.   "Taemin-ah..." Taemin stopped after a few steps when he heard Krystal calling him.   "Do you know what you have done?" She asked. Taemin turned away and tried to control his emotion and looked at her, "hmmm yes... I know" he said.   "Nini was disappointed with your decision" Taemin didn't reply her, "Nado" Taemin tried to smile. "Why did you do this?" She asked.   "Is it not good for everyone?" He asked. Krystal's guilty feeling grew inside and before she could talk he left the place.   "Yah...Taeminnie...what were talking with Krystal near cafeteria?" Jung Shin asked Taemin when he, Taemin and Kwonho gathered in the rooftop. "Why did she look sad?" He asked.   "Imo rejected Kai and Krystal's relationship" Taemin replied.   "What? Why?" Jung Shin asked in a worried tone. "How did she know about them?" he asked.   Kai was watching the kids who were playing with a ball near him as he was waiting for Krystal in the park. Kai likes kids and he always likes to play with kids. There were tons of photos and videos of him with his seven-year-old niece Kim Ra Hee and five-year-old nephew Kim Rae On. It didn't take much time for him to get along with with the kids in the park. Till Krystal comes he was playing with them. Those kids also like playing with him, he didn't see Krystal has come and watched him.   "Are you busy?" for Krystal's voice, Kai turned back.   "Oh, Krystal..." He came to her with a big smile and hugged her. They pulled away from hug when they heard kids giggling.   "Kids, she is my girlfriend," Kai said to the kids who were looking at them. Still, his hands were around her waist.   "Annyeong" Krystal waved at the kids. They started giggling at them again.   "Oppa, she is pretty," a girl said to him and they ran away with shy.   "You are pretty," Kai said and poke her nose.    Krystal could only get a smile, "Do you like kids?" She asked.   "Hmmm yes...Aren't they cute?"   "Dae...cute...” Both looked at the kids who were now playing in the new place.   "When we are married, I want a lot of kids" Krystal looked at Kai and got a smile.   "How many?" she asked.   "Hmmm...Three..." he showed three fingers, "Ani..." he shook his head, "Five...ani... seven...aniyo...how about dozen?"   "12?" Krystal exclaimed and chuckled.   "Hmmm...Double-digit is not bad, right?"   "I thought one or two," she said and smirked at him.   "Oh, one or two? Then for other kids should I look for another girl?"   "What?"   "Hmmm for other ten kids...Mina!! Mina is a good choice"   "Oh...then for those two kids also go to her...I'm going..." Krystal tried to free herself from his hands but his grip was tight on her.   Kai hugged her, "How will I go to another girl, when I love you so much, Krystal?" He said. Those words made Krystal stop struggling and smiled at him.   "Nado!" She replied.   They pulled away from hug when Kai mobile started ringing. Without removing his hands from her waist, he took his mobile from his pocket.   'Odiya?' Mrs.Kim asked from another end.   "With Taeminnie..." Kai replied.   'From when Taemin-ah started wearing skirts?' Kai got shocked and pulled away from Krystal to look at her; she was wearing a pink skirt.   "Odiya, eomma?" He asked as he looks around but he couldn't find her. Krystal looked at Kai's sudden expression.   'Come home. Now. With her' Mrs.Kim said before disconnecting the call.   When Kai and Krystal entered the living room, they saw Mrs.&Mr.Kim waiting for them. Krystal nervously entered the room, like she expected Mrs.Kim looks angry while Mr.Kim gave a warm smile at her. Krystal politely greeted them but still, there is no change in Mrs.Kim's reaction. She tried to remove her hand from Kai but he refuses to leave it and Mrs.Kim didn't fail to notice it. They sat across to Mrs.&Mr.Kim, their living room was filled with silence.   "So this is your girlfriend, Nini?" Mr.Kim broke the silence.   "Dae..." Kai nodded and gave a glance to Krystal, "I wanted to say about us soon but..." He looked up at Mr.Kim who is smiling at him. Krystal tried not to make eye contact with Mrs.Kim but Krystal's eyes couldn't help her, often it turns to Mrs.Kim to know whether her expression is changed. It is still the same.   "So what are your parents doing?" Mr.Kim asked Krystal.   "I grew up with my eomma, now she is in Incheon, me and my sister Jessica living together, I work in Alpha Construction" she replied in low voice. Often her eyes moved towards Mrs.Kim.   "Oh...Alpha Construction? Did you meet through work?" He asked in excitement, after hearing 'Alpha Construction'. Mr.Kim felt like Krystal is no longer stranger to them.   "Aniyo appa..." Kai spoke first, "I know her before itself..." He looked at her and smiled before continuing, "We studied in the same school...we often fight a lot there" he said and chuckled when he remembers his school days with Krystal.   "Dae...we did schooling together. I studied there in scholarship" Krystal said to inform them about her financial status and Mr.Kim can understand that.   "Appa, often she will be our class representative...often nagging to submit my assignment, project work...we often get into argument then..." He said their old stories.   "Looks like she is a very responsible person," Mr.Kim said.   "Dae..." Kai responds quickly with a big smile.   "So from when you started your acting before my son?" Mrs.Kim spoke her first word with Krystal in a cold tone. Those words didn't look comfortable with anyone in the living room.   "Eomma...she doesn't act..." Kai responds quickly again.   "Let her talk Nini," Mrs.Kim interrupted her. Krystal looks scared and confused because of Mrs.Kim's strange words. Krystal knew very well that Mrs.Kim will be angry on her for her relationship with her son but her words tell that she is up to something else.   "I don't get what you say, eomonim," Krystal said in low voice.   "Shut up" Mrs.Kim shouted at Krystal as she stood up. Others got jolt up for her reaction especially Krystal, it gave her shivers, "Don't act before me" Mrs.Kim screamed pointing her finger at Krystal who tries to hide before Kai.   "Jagiya..." Mr.Kim immediately stood up and stopped Mrs.Kim before she goes to Krystal, "what happened?" He asked.   "Oppa...she is the girl I told you before..." Mr.Kim looked confused, "she is the one who pushed away that old ahjumma down in stairs, and she was the one who was fighting before the store with a guy...now she has come inside our home to cheats us all..." Mrs.Kim turned to Krystal who is scared and still holds on Kai with watery eyes, "we don't believe your acting, I knew about you" she said. Mr.Kim recollected those incidents which his wife has already told him. He thought it must be some random girl but didn't expect her as his son's girlfriend.   "I don't know..." Krystal started again.   "Stop it...stop acting..." Mrs.Kim shouted at her, Krystal stopped.   "Jahiya...Let her talk her side..." Mr.Kim said to calm her down.   "I don't want to hear her lies..." Mrs.Kim angrily replied and turn to Krystal, before Mrs.Kai could talk, Kai interrupted, "Eomma..." He called her louder tone to gain her attention, "Let her talk...please..." He pleaded to her. Mrs.Kim looked silent, Kai nodded at Krystal to talk.   "I don't know what you are talking about, if I would have pushed any elderly person down and I didn't help them then it would have happened without my knowledge, regarding that fight in the street, it was to save a girl..." Krystal replied with a shaky voice. Kai recollected the incident that happened before a shop while Krystal was waiting for him.   "Don't lie...I don't believe your words..get out...I don't accept this relationship..." Mrs.Kim replied angrily. Those words made Krystal frozen. "I say get out..." Mrs.Kim screamed again. Tears rolled down from Krystal's eyes and before Kai would stop her, she ran out. On the way to her home in the cab, Krystal tried hard to stop her tears but as soon as she entered her house, tears burst out from her eyes. Krystal ran to her room and she didn't stop when Jessica called her.   "Krys...why are you crying? What happened?" Jessica tried to turn Krystal to face her. But Krystal has buried her face in her pillow and crying even harder. "Tell me, dear...I'm worried" Jessica said in a worried tone.   "Go away unnie...I want to be alone..." Krystal said without looking at her.   "Tell me, please... I'm here for you" Jessica asked again but Krystal shook her head.   "Unnie, I want to be alone...go away..." Krystal shouted as she turns around to look when she felt someone touching her shoulder. Krystal stopped when she saw Kai is sitting next to her, "Go away...I won't see you anymore" Krystal said after she again buried her face in the pillow.   "Krystal, look at me," he said. She shook her head. He forcefully turns her to look at her still, her head hung low so he lifts her chin and looked at her face. It is now red and still, tears rolling down from her eyes, she bit her lips to control her cry. "Go away...your eomma hates me..." She said.   Kai shook his head, "No I won't...because I love you Krystal" he said and kissed her cheeks. As soon as she heard his words, she wrapped her arms around his neck and started crying again.   "I'm not acting, Nini...I didn't do anything wrong...I'm not cheating..." She said as she cries, "I love you so much" she said and Kai rubs her back to calm her down.   "I know Krystal...I know...don't cry...” His words calm her down. He slowly pulled away from him and wipes her tears and cup her face, "I Love you so much...I won't leave you" he said and pecked on her lips, she smiled.   "But your eomma..." He stopped her.   "I think there is a misunderstanding...we should clear it...I will talk to her again..." He replied. But still, Mrs.Kim's words were ringing inside Krystal's head.   "She didn't accept our relationship..." She said in low voice with her head hung low.   "She will, once that misunderstanding is cleared..." He lifts her face, "We will be together...forever" he said, Krystal got a small smile. "Now come out...appa has come to see you," he said.   "Appa!!!!" Krystal shook her head, "No I'm not..." She said with pout face. Kai chuckled.   "Yah...he won't eat you...come, I'm there with you..." He said. Krystal thought for a moment and recollect Mr.Kim's talk with her, she realized he was good and spoke nicely to her, it gave her courage and she nodded yes. Kai waited for her as he sits in her bed, she was fixing her hair before the mirror and trying to hide her tears stains on her face with her light makeup.   After a few minutes, Krystal and Kai came out; they say Mr.Kim talking with Jessica in the living room. Krystal got shy to face Mr.Kim, she tried to hide behind Kai but he made her sit opposite to Mr.Kim and he sat next to her.   Mr.Kim got a smile when he saw Kai and Krystal, he can understand Krystal has got hurt by his wife's word and Krystal has cried a lot because of it by seeing Krystal's swollen face.   "Appa, she was crying in the room," Kai said. That earned him a small hit on his knees from Krystal. Mr.Kim and Jessica chuckled for it.   "Of course she must be crying...your eomma hurt her a lot...” Mr.Kim said to Kai and looked at Krystal, "Am I right?" He asked. She didn't reply but hung her head low.   "Krystal" she looked up at Mr.Kim, "Tell me what my wife was saying about you? I want to hear your side of the story," he said. Krystal looked at Kai; he nodded with a smile to encourage her to say.   "I don't know when I pushed a granny down...if I could have done like that, I'm sure I would have helped them...I think regarding fighting with a guy, recently I remember I fought with a guy to help a teenage girl who he was misbehaving with" she looked at Kai and Mr.Lee for their reaction.   "Do you hit him also?" Mr.Kim asked her pointing Kai. Krystal nodded yes while Kai shook his head. Jessica and Mr.Kim again laughed at them. Kai shook his head in disappointment when Krystal looked at him, "Don't lie...I always hit you when you do wrong" Krystal said and again hits him in his knees playfully. Again everyone laughed at Kai.   "Appa, that day she was waiting for me in a store, that time it happened, eomma must have seen her there," Kai said to Mr.Kim to divert from his embarrassment.   "Yes, that day only..." Krystal said in a louder tone, "We also met Jung-Eun Noona and Jung-Ah Noona that day," she said.   "They both know abo
