recommendations w/ realistic leads & working through trauma?

hi y'all, would appreciate some recs for manhwa wherein the leads act in a way that is reasonable for men their age. these don't need to be healthy/sane thought processes or behaviors, nor do the relationships need to be healthy. some examples would be Hate Mate, Yang Ilwoo and I, There are No Bad Dogs in the World, Love For Sale, Ouroboros, One Room TA, Lovesick Dog, etc. would prefer works with characters who have some baggage and, if possible, who are also working through that baggage, however imperfectly. thank you!
