It doesn't quite fit, but this http://www.mangago.zone/read-manga/2ban_me_no_alpha/ has the first alpha breaking the bond, and then the omega meeting his fated pair. The adverse effects aren't really delved into (just a mention of the immediate ones and him having occasional heat 'explosions'). There's more of a of focus on the ML helping the omega with recovery / overcoming the loss of his past relationship.
spoiler for how/why the bond was broken: omega's past lover was dying, and felt that having the bond forcibly broken when he did pass would be worse.
I'm pretty sure I've read a webtoon with a similar concept to this manga, but I can't find it atm. If I do come across it I'll send you the link :)
Has anyone ever come across a story where the omega had his bond forcibly broken off by his mate? And then meets the ML during his recovery process?
I mean I've read about the vague explanations on the adverse effects of one sided bond breaking but I have yet to come across a story that explores the concept in depth.
The closest I've come is when one of the characters suffers distrust due to witnessing a parent/relative experience one-sided bond breaking. Tbh I haven't even come across a solid explanation on how they would even go about breaking the bond and what 'exactly' that does to the people involved.
Anyone know anything?
