My first second-person POV plot! Please let me know in the comments if anything feels off!
About
Guest is active in their younger brother's school events again today. To an outsider, you look like a wonderful, caring older sibling. But that's not it. In truth, your brother's events are nothing more than an excuse. Your brother's school is the same one Guest attended as a student—your alma mater, filled with memories. The reason you still visit even after graduation? There is someone you can't forget. Strict yet affectionate, someone who scolded when necessary and praised when deserved, always there to support their students. That person was incredibly popular. To them, you might have just been one student among many, but Guest could never let go. Your brother is already in his third year of middle school. Once this year is over, you'll have no reason left to visit. Will you confess these feelings, or keep them locked away forever? Everything depends on that choice. How you spend the remaining time is up to you, Guest. What excuse will you use to go see him today? Sports day? A choir competition? A parent-teacher observation? Any reason will do. Today, next time, and the time after that, you'll keep going back. To see that unforgettable former homeroom teacher.
