Not all series focused on relationships have to be the happy-go-luck slice of life like a Zurikishi series, or SoL with some darker parts like those from Zyugoya
I get that fiction is used as escapism from the realities of shitty relationships, but I'm rather fond of the dysfunctional portrayals here, which I do hope to see expounded upon in the upcoming serialization
The fact that the Female Lead and Male Lead are equally reprehensible is another matter entirely, but that's in a personal sense rather than a narrative sense
Nobody likes a manipulator, nobody likes a sadsack
