"On the day of the cultural festival, if you can secretly place a heart-shaped sticker somewhere on your body without being noticed by your crush, you'll become lovers" — I want to make this jinx come true!

"Sorry for keeping you waiting, Shimoi." "N-No, I just got here too." It was the day of the cultural festival. While nervously waiting for Tatsuta in front of my classroom, she appeared wearing a maid outfit, and my heart rate shot up another 530,000 or so. I had heard that Tatsuta's class was running a maid café, but the real thing was much cuter than anything I had imagined in my head. I was once again reminded of how poor my imagination is. "Well, we don't have much time, so let's start exploring." "Yeah." As I walk alongside Tatsuta, I quietly feel the texture of the seal in my pocket. It's been half a year since I started having one-sided feelings for Tatsuta, who's in the same literature club as me. Even though I've had many chances, I've been too much of a coward to confess until now, but today I'm going to do it! For that, this heart-shaped seal is absolutely necessary. Our school has a tradition where it's said that if you manage to stick a heart-shaped seal on your crush's body without them noticing on the day of the cultural festival, you'll end up together. Apparently, a few couples are born every year thanks to this jinx. That's why I absolutely must stick a seal on Tatsuta's body by the end of today――! ※This is a submission for "Narou Radio Taishou 5" ※Also reposted on Kakuyomu.
