Jaebum decided to go back home after meeting Jisoo. He looked cool earlier but he can't deny the fact the he was very worried of Jihyo right now. He knows that his girlfriend is the type of person who wants to do everything what she can to help out but in the expense of stressing herself too much in the process. Besides, he has no idea on what state she really is in and if she has someone over there to at least talk to. His mind wanders about the "ifs" when he got a phone call.

JB: Jihyo-ya!
Jihyo: I'm sorry oppa about earlier. I hung up on you.
JB: Don't worry about that. How are you doing right now? I really miss you.
Jihyo: Don't worry about me. My family is here and everyone is taking care of me well... I miss you too.
JB: I will go there.
Jihyo: No! I mean, you don't have to.
JB: When will you be back?
Jihyo: After I finish my work here.
JB: And what would that be?
Jihyo: Something that has to do with my sister.
JB: Like?
Jihyo: Sorry I can't explain right now. But I have to fix things.
JB: So you are fixing your sister's problem?
Jihyo: I'm just helping out. I'm gonna see you soon.
JB: I'll wait for you. I love you Jihyo.
Jihyo: Thank you.

JB let out a sigh. He is contemplating whether to tell Jihyo that her sister is here or not.    He still wasn't sure the seriousness of Jisoo's problems to make her looked like mess right now. Obviously, she really needs help, but he doesn't want Jihyo to suffer because of it. But Jihyo is still Jihyo. She would still help out her sister. JB felt like he's in the middle of it.
