The Anime Lad
Futaba Yoshioka enters high school determined to seem less feminine after girls ostracized her in middle school. The performance helps her avoid jealousy. Then she meets the boy she once liked, now using the name Kou Mabuchi. He remembers their old feelings but says things cannot be the same. Nostalgia has failed its compatibility check.
Super Eyepatch Fox
Futaba acts deliberately unladylike so her new friends will not reject her. Then her middle-school crush reappears as Kou Mabuchi, familiar but changed. He admits their old feelings matched and closes the door on simply resuming them. Their unfinished connection meets the personas built during three years apart.
Gigguku
Futaba has redesigned her whole school personality so girls will stop treating her like competition. Then the one boy she could never confess to walks back in under a new name. He remembers. He felt it too. He also says the past cannot simply restart. That is an entire wall of teenage emotion arriving in one reunion!
Father's Basement
Futaba’s attempt to secure friendship by acting unlike herself is frustrating because the logic is recognizably teenage. Her reunion with Kou makes the same point from another direction. He is the boy she remembers and also someone who insists that time changed the situation. The romance begins with both of them performing versions of themselves they may not trust.
