Minho thought that Krystal might have been wandering around the whole building since there was a nurse running behind her, she pushed the nurse away and tried to hug Minho but Kai embraced her as she moved towards Minho...

Krystal: What are you doing? Who are you?

Kai: It's me Krys, Kai...I know it's been a while but--

Krystal: *pushes him away* I don't-- Wait...K-Kai?...

Minho: Do you know him?

Krystal: I...kind of...

Kai: I met her once 3 years ago, it was a small meeting, though. We were at a party, and--

Krystal: Don't say more...Shut up...he doesn't need to know about that..

Minho: Why?

Krystal: It's something you don't really need to know...

Minho: If you think I will get hurt by knowing, you're wrong. I don't really care, I just want to know

Krystal: *sigh* There are other ways to make me forget about you, you know?

Minho: Sorry...I didn't mean it, I'm just kind of angry...

Krystal: I guess...Sulli left again right?

Minho: Yes...But she doesn't want me to find her.

Krystal: Why?

Minho: She feels guilty for all that has happened, even if it's not her fault. I guess she---

Kai: I think I know how to find her

Minho: Huh?

Kai: She left a letter on her mansion in the mountains, I didn't read it, it said it was for Minho Bezarius, is that you?

Minho: Yes. I will go there!

Krystal: But--!

Minho: Just stay with Kai, alright Krystal?

Krystal: I--!

He left running and Krystal tried to walk away from Kai, but he grabbed her wrist to stop her, she glared at him...

Kai: You and I have some issues to talk about.

Krystal: What? What are those issues we have to talk about?

Kai: I want to know why you left that night...

Krystal: That's none of you business...

Kai: Why didn't you tell me that you were a vampire huntress?

Krystal: Shut up! You didn't need to know! I was just there that night because I was in a mission, what happened with you didn't mean anything to me

Kai: There are other ways to make me forget about you, you know?

Krystal: *glare*

Kai: I'm just using your own words against you

Krystal: Just go away

Kai: *holds her by her arms* Are you mad at me?

Krystal: Don't talk as if we were close... *pushes him away* 

Kai: Just tell me sincerely

Krystal: I can't let Minho go on his own, what if---

Kai: That's none of your business, you're not his girlfriend.

Krystal: *slaps him* Shut up! I already know that!

Kai: *holds her hand* I'm sorry if I offended you *kisses her hand* 

Krystal: *pushes him away* Get away from me! I hate you! If I hadn't met you that day...I...I....*walks away* 

She went back to her dorm, Kai got up and followed her, he knocked her door a lot of times but then he sat on the floor and waited for her to open. She was crying on her bed but after a while she walked out of her room, Eunhyuk was talking with Kai....

Eunhyuk: We need to find Minho before they do

Kai: I understand. I'll take you there.

Krystal: Did something happen?

Kai: The other members of the royal families sent the hunters to catch Sulli, they're probably going to look for her in her house in the forest, where Minho is going.

Krystal: What?! But they can't hurt him, he's a hunter too!

Eunhyuk: The thing is that he's also a vampire, and the Principal ordered us to get rid of him and you, because you're related to Sulli. They might probably fire me too

Krystal: What?

Kai: Which means we have to get all of you out of here

Krystal: What?

Hunter: There they are! Catch them!

A lot of hunters chased after them, Krystal almost fell but Kai carried her "princess-like" and grabbed Eunhyuk's arm, then he used his powers to disappear and teleport themselves in front of Sulli's house, the members from the royal families were already there, as soon as they saw them they hid behind some bushes...

Krystal: Do you think they saw us?

Kai: I don't think so, but apparently they haven't found Minho nor been able to open the door

Krystal: Looks like that

Eunhyuk: What do we do now?

Krystal: I--

Kai: Let's take this moment and talk about what happened 3 years ago

Eunhyuk: Guys, I don't think this is--

Kai: Shut up!

Krystal: There's nothing to talk about and this isn't the time to talk about that

Kai: I don't care, it's now or never

Krystal: What? What do you want to know?

Kai: Why did you kiss me? Why did you left? Why?

Krystal: I...

*Krystal's memory: I had gone on a mission, Minho wasn't asked to come with me, I had to go to a party where there were many vampires disguised as humans, I had to get rid of them without causing a ruckus in the party. It was a college students' party, there were a lot of them, I managed to find the vampires but it would have been dangerous if I took one of them out so I decided to try to fit in the party, I started talking with a guy...

Me: Hey

Xx: Oh, hey

Me: What's your name?

Kai: I'm Kai, and you?

Me: Kry--Soojung

Kai: I see, I haven't seen you before, who invited you

Me: Well, a friend of mine, Minyoung, invited me but she's with her friends

Kai: Ahh, I see...where are you studying?

Me: In xx University, you?

Kai: xx University.

Me: Ahh

Kai: Do you want a drink?

Me: Sure

Before I knew it, I found myself drunk, it was all because of Minho; without noticing I was flirting with this guy, Kai, he flirted with me too. I was too drunk to even remember why I was there, I forgot my mission, I knew I was going to get scolded for that but I wasn't in my right mind then.

*Actual moment

Kai: So?

Krystal: I...I was too drunk, I forgot why I was there...I had a mission that's why I left, because I realized that I was doing something very stupid. I'm sorry if I gave you the wron signal

Kai: Is that it? Didn't you feel anything when we kissed?

Krystal: I was sad, ok? I was depressed because of someone else, and trust me, alcohol isn't the best thing for someone who's depressed

Kai: But you still flirted with me

Krystal: But it didn't mean anything! I wish I hadn't met you that night!

Kai: You don't...you don't have any idea of what it meant to me...

Krystal: You should know that it always happens, you go to a party and kiss a random guy/girl and then you forget completely about them.

Kai: It wasn't like that to me

Krystal: Then you're just stupid...You're a lovesick fool...

Kai: *kisses her* Will that change your mind?

Eunhyuk: Guys! Stop it! They---

When they turned they saw the young vampires staring at them, preparing themselves to attack them, or force them to tell them where Sulli was...
