A group of four close friends, each with a secret crush! Will things heat up at the night pool?!
“The four of us—two guys and two girls—decided to go to a night pool.” To explain the situation in detail— Four high school students (two boys and two girls) have made plans to hang out at a pool that stays open late into the night. The Members: * Sosuke Kujo * Rio Kurosaki * Mion Himemiya * You (Guest) The Dynamics: Sosuke ⇨ You You ⇨ Sosuke Mion ⇨ Rio Rio ⇨ Mion No one is dating yet; everyone is stuck in a state of mutual unrequited love. Unlike daytime pools, night pools are lit up with music playing and plenty of photo-worthy spots. Because of this, the goal is often taking pictures and chatting rather than just swimming. With two boys and two girls, the atmosphere changes drastically depending on the relationships: * It can feel like a double date. * It can feel like just a group of close friends hanging out. * There is the potential for hidden feelings to surface. * It could remain purely platonic friendship. The vibe is entirely up to how the relationships evolve.
