I’ll admit this first one is a bit fucked up since the og ml is genuinely a very mentally ill person albeit at the same time ‘not’ a good person who repeatedly dies over and over and doesn’t even remember it, but holy shit the one part where the fucking mc pulls out a gun and shoots him broke me but god it was hilarious in an unexpected fashion

this second one? honestly the mc kinda comes across as annoying at first but she’s very loveable imo but oh my god the ml is such a dick from the start but it’s the ml’s wife that I’m sorry but I couldn’t sympathize with her (even though the story at first tried) because girl, you cheated on him and tried to pass off another man’s baby as ‘his’ and didn’t expect him to basically say fuck you when he inevitably found out and not ever want you back? c’mon now
very pretty art though! so it’s fun

this one is similar to the previous one plot wise but this ml isn’t a complete piece of stinky shit and actually sort of becomes nice later considering how fucked up the story becomes, aka the mc has a miscarriage at one point and understandably is incredibly depressed regarding it

I dunno, this one kinda made me cry with its premise aka the mc is really depressed and all the guys in the story pamper her and what not, it’s sweet? but I love the mc since she’s relatable and it’s clear why she’s the way she is

this one? it’s the ml going after the mc this time, low-key such a comfort read

uh.. the ml is literally fucking young shakespeare so that’s how we’re rolling with it, but minus the mc kinda being.. annoying? it’s really good

final one since I think I’ve given enough, but this one felt the most realistic and just.. man what more can I say?
