Kai didn't go to school the next day. His friends told Chaeyoo that he wasn't in a good mood lately when they visited him. Chaeyoo felt guilty because of their argument last night.

She went home upset. She went straight to her room after greeting her mom and Yoongi. She was about to text Kai when the doorbell rang.

: Could you please get that, Chaeyoo?

Chaeyoo groaned before she went to open the door. Kai stood infront of their house whish surprised Chaeyoo.

: Kai?

: I wanted to give you your math book back. Thanks for letting me borrow it.

: Kai I-

: Oh who's this?

Then Yoongi came out of nowhere and joined.

: Who is- Hueningkai my bro!

: Hi hyung

: Did I miss something?

: Aunt, this awesome kid is Hueningkai. Chaeyoo's schoolmate. And also her piano tutor.

: Oh nice to meet-

: No!

They all stopped and looked at her. Even Kai was surprised.

: Mom, oppa...

They raised their eyebrows waiting for her to continue.

: He isn't just a schoolmate and he isn't my piano tutor either.

Her heart started to pound even faster. Her nervousness got the best of her.

: Kai is.....my boyfriend.
