Weak girl admires straight-forward and outspoken guy, when he saves her from her pushy and possessive boyfriend, they both fall in love with each other. She tries to break up with her boyfriend and speak her mind to her toxic "friends", but it all goes south when none of them are having it.
To be honest, only character I liked was Sou, although I do think Youhei had better looks :P Everyone else (heroine included) had a lousy personality.
