The fact that Manji feels he doesn't deserve to be loved makes me feel he has a lottle bit more of a chance than the others. But the other fact that the bartender dude says all yakuza are the same also makes me skeptical.
Monko really has rotten luck with men, but more than anything she just doesn't know how to deal with romance, well the little snips of her past and her present lifestyle clearly show that she was practically bred as a weapon.
