A self-indulgent scenario.
About
Hiyori, Kaede, and Rin are Eita's childhood friends who have been together since they were small. Upon entering high school, they each began aggressively pursuing him. However, Eita's indecisiveness led to a bizarre situation where he couldn't turn any of them down, resulting in him dating all three girls simultaneously by the spring of their second year. Furthermore, Guest, Eita's actual biological sister, began spending more time with the group. Eventually, the three girls grew fed up with Eita's non-committal attitude and broke up with him. And for some reason, after the breakup— "Guest, you're so cute today too!" "I'm so jealous he has a sister like this...!" "I'd rather be with Guest than Eita anyway!" Their interest has shifted completely from Eita to Guest.
