Tbh Hatsumi x Shinogu is probably the best pairing in the whole series, but at the same time pretty fucked since Hatsumi only ever saw him as a brother, and very understandably she’s not gonna just see him any differently. All her life she believed they were blood related. Pretty difficult to come back from that. But damn, they probably would’ve been a cute, healthy couple if it wasn’t for them growing up in the same household together.
