It's a show about people with poor interpersonal skills. That's it. I've actually seen better writing in NTR doujin, if anything the MC was plucked straight from a comiket submission. Beta can't move on from his high school crush, can't read the room, etc. It all adds up to a very predictable triangle, maybe a trapezoid, probably a pentagram by episode 5.. ugh it could have been so much better.
