Haa.. this is purely a truly suffering 
Based on the title. Reading a single chapter feels like a sin.
What goes on these writers minds open cuckolding became a genre damn
god this manga is depressing, and it all seems kinda dazed as another person said, and very confusing. plus, it never seems to progress. however, it is pretty good despite that, so give it a read if you have time and have the mental stability
That title is disgsuting🤮
This is messed up. The mid chapters that were released, that seemed to follow the guys perspective, raised more questions than answers. The series feels very wishy washy with what is happening and everything feels like its in a daze. The main character is just completely broken mentally and has no concept of happiness so she clings on to what she thinks is love. If it weren’t for the mid chapters I would think the guy was the antagonist, but now it seems the sister might be if unintentionally. I don’t see this series giving any answers anytime soon, so the theory Im sticking with is that they are in Hell. Since the one she loves will never love her back but will be stolen by the one everyone loves, and the guy forever see’s the one he loves slowly become disillusioned with him and him not having any control to stop it and not even consciously realizing it.
Yadda yadda
I read a bunch of spoilers from someone who read the novel after reading these 18 chapters of idiocy. TLDR of the 18 chapters is: mc is a pushover and suffers, the end. The art is good but the story is dumb and if it follows the novel it might get worse.
if you’ve read the current chapters, here’s a spoiler from Reddit to put you out of your misery
most of the series is pure suffering, in the end Crow is the final ML and he spends an eternity trying to find a timeline where MC can be happy. In the last timeline (at least as of now), the MC, her sister and her fiancée end up avoiding the sister’s death by bandits, which was planned by a minor character that appeared in a previous timeline and apparently has a sort of conspiracy going on involving the sister being a lost princess and yadda yadda, however MC ends up dying again during the struggle, for Crow to find her after she has died. MC then has a bit of a out of body experience where she witnesses Crow’s attempts to save her in different timelines (Crow can travel between timelines), and after that feels trip she somehow revives in the death by bandits timeline. As of the latest chapter, MC settled to try to live happily with Crow and is planning to fake her death to her sister and fiancée so they can live together
It’s not finished yet and as of now there’s a couple of loose points that I hope are going to be addressed, and things can still go to depression land again, but so far it SEEMS like it might end in a slightly positive note.
Another story of a victim, which would have been fine, except for that little thingy of the time loop, why in the hell would someone choose to torment themselves with that kind of shitty people?
Wow that title
