Oh my god, never in my life have i seen such stupid female characters o.o
First Saionji, the start of all this shit and madness! She deserves to be killed..
Kotonoha, Soooo Naive!!! She exactly the type of characters who gets cheated on without her even realizing it -.- but i like her more than sekai..
That new character, Roka i think.. An even more naive girl.. geez, i hate her.
I can't seem to figure out what the hell they found in makoto.. he isn't even handsome or cute. is it inside beauty? No, he does not have.. Outside beauty maybe?
They are sooooo naive and stupid, especially sekai -.-
