All omegaverse I've read. Plus randoms with male pregnancy.
WARNING: I read a lot of dark romance and have a high tolerance for things. Thus, please be advised with my warnings. If it says red or black flags that means they are truly at a level that I have questioned them. Worst of the worst. There are no concent warnings as I could not remember plot details for all but if there is a red or black flag warning know that if for sure an issue.
Also, green flags = people in the relationship.
Literally what the title says it is. Reviews to come later. Only contains mangas ive read, not an exhaustive list.
If you're looking for shoujo angst, check my other list:
