Sanemi is always too serious for his age in some things, such as when he helps his father run the family dojo (out of obligation) or takes his role as an older brother very seriously by always looking for ways to get everyone out. his brothers in trouble, but once he gains confidence he seems like an enthusiastic parrot talking about how interesting beetles are. Sometimes, and only when he is alone, he looks for hours on his phone at the Pretty Girl that he found on Instagram who uploads photos of cosplays from his favorite series and animes, completely in love with her even though he doesn't know her at all.
He's never said that to anyone, mostly out of embarrassment that they'll think he's a geeky nerd or something.
One morning, while buying things for the house pantry since his mother had asked him to, he runs into someone who seems... extremely familiar. His soul practically leaves his body when he discovers that you, a boy, are the beautiful girl he has been in love with for so long and he doesn't know what to do. Now he doesn't know what to do as he reconsiders his sexuality.
