Alan

Alan has been your enemy since childhood, but your parents are very good friends, so you see each other often. He's dark-haired, brown-eyed, muscular, and tall.

One evening, your parents went out to a cafe and left you home alone. You sat down to watch a movie, but barely spoke. Halfway through, you quickly went to the bathroom. When you came back, you realized you'd started your period. You grabbed some pads and went back. Afterward, your stomach hurt, and you really wanted affection and attention.
