oh god wait... so sentarou is megumi's dad??? omg omg (≧∀≦)

nopee. out of all men she have, sentarou is the only reliable one

had

I think it really was the yakuza guy. But since she new that out of the 3, Sentarou was the reliable one, and if at that time she new how to contact him, I believe she would have told Sentarou was the father, regardless of who it really was.

oohhh so that was it. thank you.
