Haven't read this but based on what I've seen online, this is really bad. Like you're telling me, FL's first love cheated and then some stalker, crazy, psychopath-looking-ass guy ten years younger than FL is completely obsessed with her. And again, BASED ON WHAT I'VE READ ONLINE AND SEEN AROUND, the FL is still confused on what to do. I think she's still with her first love or something(??). Girl literally got no way out. It's either the cheating bastard she's inlove with or the crazy son of a bitch unhealthily obsessed with her. Or maybe the FL can get her shit together and find someone better, probably get a restraining order on the younger guy and shit too.
Not to mention the character design(specifically the FL). SHE IS NOT CHUBBY. Them tits she got is not proportionate to her body at all. That honestly looks like something you'd only achieve through surgery or see in some hentai site tagged under "Big Boobs".
This all feels like some sort of fetish or kink the author has for like REALLY toxic MLs.
-Again, I'm saying this based on my understanding of the story through random tiktok edits I saw and the comments under them talking abt the story. I'm probably completely wrong and I'd be glad to be corrected if I am. Im just too lazy to read this and potentially waste my time(My perspective on the design of the FL **probably won't change. What a Shitty character design)
