At school, time to go home and all the students are walking outside and go have fun. Sungjong is staying in the front door waiting for Hayoung. It's 3:05 already and Hayoung didn't come out. He start to get a little mad because he hate waiting the most. He about to leave but Hayoung come out and he turn around to see her. 

Hayoung: I am sorry. Mr. Kim ask me if I can help him if I can bring his stuff with him go upstairs.

Sungjong: You are just a slow turtle. If you don't want to come then don't.

Hayoung: I really waste my time to come here and yet yell by you. I am always do what I say or promise to someone but if you going to do this then I am going now. I don't get time to get yell by you.

[Hayoung start to walk but Sungjong hold her hand.]

Sungjong: I-I am...sorry. I'm just don't get use to wait for someone. Please don't get mad.

Hayoung: Only this time and if other time, I will get mad and won't forgive you. 

Sungjong: Next time it won't happen. Let go!!

[Hayoung wait for Sungjong to walk first and she will follow him but he turn and look at her. He smile and hold your hand right then pull her closer to him and walk together with him.] 

I don't know why but being with Hayoung make me feel so happy all the time. This is the first time I say sorry to someone and that is Hayoung. I am keep thinking what wrong with me. I feel like I am not the same person because of this girl. I am one years older than her and I feel like I don't want to loose her. I always hope we get the same class but we never get the same class which I hate a lot. Everytime I see her, I want to bother her because she look cute when she get mad." Sungjong though and keep walking with Hayoung holding hand side by side.
