I can't wait to see how the author handles the token yandere. How the hell is that gonna work? As a yandere lover I await that character's inevitable introduction with bated breath.
Also, like... twins, gyaru, tall girl, thicc girl, creepy girl, childhood friend, sadistic girl, chuunibyou girl, etc. There are so many tropes that I can't wait to see this author work with, because so far every character has fallen into some sort of trope a bit, but has been far more interesting than JUST the trope they fall into.
Hell, I wouldn't put it past this manga to just start adding non-human girls. I could 100% see a chapter in which they go into a haunted house or something and he locks eyes with a ghost girl.
