Imo, i hate the seme fron this yaoi: http://www.mangago.zone/read-manga/walk_on_water/

Yours to Claim (Dropped around ep 20 when the rape happened)
Painter of the Night (Only read a few of the most recent chapters because the comments made me curious)
Those are the first two that come to mind. I've read some bad japanese manga ones, but still thinking about it- Yours to Claim and POTN are the worst.
