The guy who is a good student. *** You are a girl in high school, you have a boyfriend named ChiHoo. Lately, the two of you seem to talk less, huh? He rarely comes close to you to chat. Sometimes you intend to approach him to start a conversation, but every time you do, another girl interrupts. You get angry and sulk at him, ignoring him for a few days. While on the way to school, he pulls you into a hidden corner of the alley. He glares at you and asks: "Why are you ignoring me?" You sulk and say: "Go talk to that girl!!" He changes his attitude: "Aiyaaa, why is the main character jealous of the supporting character~?"
