Argh this is so cute

I don't think there's going to be an actual story that's incredibly similar to this one but here are mangas with questionable lovers and a guy picking the better choice:

Also has a guy with an abusive bf + a friend, apparently a more painful ver of this manga according to another reader.

Uke had a string of abusive lovers, settles with a good guy:

Not physically violent, more like neglectful and uses him at convenience according to uke, but not enough screen time of the initial bf to even see it happening. Seme's a pure bean though, real cute.
