[Irregular updates] Blurb: In high school, Funakoshi Meisa had a secret relationship with the school's delinquent ringleader. They played at "pretending not to know each other," fooling everyone with their superb acting. No one found out, even after they broke up. Years into her career, Funakoshi Meisa got back in touch with her ex-boyfriend to discuss an internship for her younger cousin. The two arranged to meet at a restaurant, where they happened to run into a high school classmate The classmate exclaimed, delighted and surprised, "You're still together!" Funakoshi Meisa: "Huh?" The classmate said, "Back in school, we all thought it was so cute how you pretended not to know each other." Funakoshi Meisa's smile slowly vanished. "???" Just how pointless had her secret relationship been? * As Kumagai Mitsuo's college roommate and current colleague, Usahara Tobikichi could never understand how this guy could get along so well with the first love who'd dumped him. Later, this was Kumagai Mitsuo's answer: "Because I still love her, idiot." Reader's guide: ★ Inspired by Kumagai saying, "I don't have any wholesome romantic experiences I can tell the kids about" while I was reading the manga. (Ahem! But overall, it's very wholesome!) ★ Written with love for fans of this series. ★ The heroine is imperfect, the characters are flat, and the supporting cast are just props. If that bothers you, please stay away! Although the story doesn't involve much of the original plot, I don't recommend reading it as an original work. The timeline is a mystery, and there are lots of headcanons. *Who's writing about Life Lessons with Uramichi Oniisan in 2026? Oh, it's me, hahaha. *Happy ending Theme: Be a good person and have a healthy relationship
