Plot summary: Kang Jiwon is sent back into her past self's body after discovering her husband cheating on her with her best friend. She aims to change the trajectory of this new timeline by orchestrating their union early this time. Overall score: 7/10; The idea is interesting and the art is good, but the characters sometimes fall too deeply within their own tropes to be believable. Sumin, who is Jiwon's homewrecker best friend, is quite cruel and manipulative: where this is interesting in the story is how Jiwon sees the manipulation quite clearly the second time around, but where it falls flat is in how anyonecould stand to be around Sumin for two seconds believably. MAJOR spoilers here to exemplify: Sumin eventually fakes a pregnancy with Jiwon's fiance which, although just broken off, is extremely suspicious and traitorous to their friendship. Talk about breaking girl code!! Jiwon is understandably trying to build the most effective revenge of having her ex-fiance and Sumin marry, but I wouldn't even look at Sumin again if she tried the pregnancy route like that, revenge or not. Some of the other characters also have some strange characterizations and moments that seem like they are making unrealistic decisions, but in the end, the revenge is indeed well sculpted and the story culminates into a justified whooping for the antagonists.

TLDR; the revenge of a scorned wife unfolds well, but can get somewhat lost in how insufferable the antagonists are. For what the story does well in getting justice for the protagonist, it loses a bit more in realism (aside from the whole 'back in time' thing, of course).
