Rin and Hanayo aka Nyan and Pana are known to be the astro twins or the partners in crime as they are always seen together. Almost like the two are sewn together in the hip since birth. Of course,as cliché as it is.. People find themselves falling inlove with their bestfriend. Opposite or same gender. Maybe because you realized they have something that actually attracts you in a romantic way. Since the two of you are always together and are very open with each other,you'd know them better. And sometimes,having a crush on them turns into an experience. Of course that's what happened to Rin and Hanayo in this story. I'm glad they admitted they're gay for each other.
