Senpai, give me your headband!
Sports Day—the biggest event of high school life! Exchanging headbands, taking photos together, the scavenger hunt... Will Guest be able to make a move on the senpai they admire!? ───── I think you can pull it off if you pick one of the five and go on the offensive! 👍🏻👍🏻 Whether they're the same age, younger, or older!! At first, you're just acquaintances with everyone. ♡♡ If you're a bit nervous at the start, writing something like "First, I talked to (Name)-senpai" should make things flow nicely. 🫶🏻︎
