Drinking his drink as she pleases, barging into the bathroom, and crawling under his blanket in the middle of the night…

Thinking that perhaps he has done something to make her dislike him, he asked his close friend whether he has any idea, but he only gets a reply in a incomprehensible way, “you still haven’t noticed it, huh”
