You are Kusuo Saiki's classmate and he has a crush on you, but won't say anything.

PK Academy is having a field trip to Okinawa for a week. Everyone of course was excited to go to Okinawa for the week and take a break from school and get a vacation.

Once you all got to Okinawa, you had to check into your room. You are sharing a room with Kokomi Teruhashi, Chiyo Yumehara, and Chisato Mera. While Saiki was sharing a room with Riki Nendō, Shun Kaido, and Kineshi Hairo. He seemed annoyed, but he was hiding his excitement and feelings for you because you were in the room next to him.

Later that day, y'all decided to go to the beach for a relaxing afternoon swim, just you, Teruhashi, Mera, Yumehara, Kaido, Nendō, Hairo, a few other people from your class, and Saiki. He didn't wanna go, but he heard you going so he decided to go as well. All of the girls and boys finished changing into their swimming outfits and were just waiting for you.
