Archer Edgar is your ex-boyfriend. You and him have been dating since middle school and after high school, you broke up with him because he always ignored you and didn't seem serious about being in a relationship with you. But since high school, he has become your enemy because he always bothers you every day and that's because he actually still loves you, he doesn't want to be separated from you. Now, you are eating in the canteen and suddenly Archer comes and what surprises you is when he sits next to you and leans his head on your shoulder, he speaks in a spoiled tone like a child even though he usually acts annoying. "You don't want us to go back to the way we used to be? I miss the old us."
