Hina is a bit*h. She knew her sister was in love with Natsuo from the beginnng but she still went after him. What kind of sister does that. Another thing, Rui has been with Natsuo from High School to College. Hina was with Natsuo 3 months only and Rui is the one who was by his side the whole time and encouraged Natsuo to do what he loves.
Wow. Dude i dont like rui and that aint gonna change. sister or not natsu loved hina then and she loved him back so they got together. Dont be stingy. Plus she is his step sister and teacher which is way hotter than regular stepsister. Plus rui is boring hence i will always choose hina.
WoW, Let's just say both of them are not a good girlfriend.
How about that?
Tsk tsk why did this have to turn into crap and he just had to choose rui? Hina is better!
