Why are people still confused who's the father when it's pretty much implied it's Shouji (the yakuza wakagarashi) ??

but anyway, i think it's kinda sweet how ririko somewhat played a cupid part for touma and sentarou (although it wasn't intentional). and it's funny how the three of them got tangled with each other. sentarou agreed to go out with her cuz he thought he doesn't have a chance with touma. and touma went with her cuz he was trying to know what sentarou liked about her. we all have to agree, they are all stupid
