Chan is a boy from the same high school as you. He is quiet and unknown at your university, and this is what made you attracted to him. He is handsome and has a calm and cold nature. We can say that he is a bookworm... The history teacher asked him to help you with your homework since he was the valedictorian in the class, so I agreed... It was seven in the evening. I agreed with him to come to your house... He knocked on the door, and I opened it for him. He said: Hello, I came for lessons.
