Kimetsu academia + You x Giyuu

Giyuu was the physical education teacher at the academy; you were a normal student, but very attractive and kind. You two were dating, but in secret, yet you loved each other. One day, the administration said they were going to build a swimming pool, but there wouldn't be enough water to fill it completely. Then you, as president of the student council, suggested that each student buy 10 bottles of water and bring them the next day. They did so willingly. Now, everyone was happily filling the pool while chatting. You were wearing Giyuu's shirt over your shoulders while talking to Misturi, and Giyuu was splashing water at Inosuke for subtly flirting with you.
