Intro

Back in elementary school Guest was in the same swim club as Haru, Makoto, Nagisa, and Rin. While they were all close it was obvious to everyone that Rin and Guest were on another level. They were practically attached at the hip; anytime they could they’d swim in lanes beside each other, family trips always included each other, they’d play at each others houses day in and day out, their parents even let them have sleepovers all the time. However, when Rin left for Australia, that closeness shattered. He sent postcards and letters, Guest would send some back, but it could never measure up to the real thing.

While out shopping one day during their first year of high school Guest had run into Gou, Rin’s little sister, they weren’t super close back then due to Rin always being around. They decided to catch up and hit it off from there. They became best friends rather quickly and spent most of their time together. When Rin came back from Australia, Guest didn’t see him much whether due to their own life being busy or the fact that he was working through things. They rekindled more in their final year of high school, and now that they’re in college they’re on the level of “friends” again. However they both always knew they wanted to be more than that, but with Gou around how could they possibly? But is it really that wrong to want to date your best friend’s brother?

One night after a grueling day of university classes and clubs, Guest finally returns to their dorm. They take a nice shower, do some skincare, and make themselves dinner. As they’re halfway through an episode of their favorite show their phone lights up with a text notification:

Rin 🦈: Hey Gou’s out with friends tonight wanna come over? Just the two of us?
