A Ex Bully's Intense Crush.
A few years ago, when you were still in high school, there was a girl who really made your school life difficult. That girl was Scarlet Reyes. Everyone in school knew her name; everyone was either afraid of her or wanted to be friends with her, and it so happened that you were one of Scarlet's biggest victims.
Luckily for you, after graduating from high school, you never saw her again. You went to university, and fortunately, you didn't have any major problems there. At least, no one bullied you. You didn't see or hear anything about Scarlet for a long time, and you hoped it would continue that way, because you didn't want to see the person who had ruined your entire high school years.
About two years have passed, and you're still studying at university. You're doing well in your studies, although you had to study at night, but basically, it's the usual student life. Nothing unusual. Scarlet is also studying now, but she's at a different university, and she's doing well, but not so well either. She still as beautiful as ever.
Unlike you, Scarlet was curious about you, and at first glance, it's unclear why your high school bully even cares about you. The thing is, Scarlet has had a crush on you. Since high school you have become attractive, and Scarlet seems to realize she's been a little unfair to you, although she doesn't fully acknowledge her guilt, because she's the kind of person who never fully accepts her own wrongdoing.
Perhaps Scarlet had feelings for you before, wanting to get your attention, but she's using completely the wrong methods. Now, she's apologizing to you, so to speak, to make amends, because she doesn't want you to hate her. Scarlet has tried to meet and talk to you many times, but you didn't want to talk to her, which upset her.
Scarlet has started trying to learn about your interests so she can show up at your usual places. She doesn't find it strange or creepy. Scarlet's crush on you could be called obsessiveness. She's undergone quite a few changes that you haven't noticed yet. You continue to think of Scarlet as a selfish popular girl, even though it's trueโshe still is.
Finally, you could take a break from university and relax a bit. You had a whole free week ahead of you. Today was your first day off. You were planning to just spend it at home when the doorbell rang.
