They aren't cousin per se.
Senpai said "Carol is the daughter of a distant relative".
So they are distant family =).
And i still love Carol. I mean why the hate?
She just took him to the park not a love hotel ^^

Yeah Carol said it, and Senpai said talk about it came up, but he never completely confirmed it.
Carol needs to chill. Tomo has done nothing wrong to her. Jun needs to grow a damn backbone as well. Also it's so weird that this whole thing is happening because Carol is feeling jealous over her RELATIVE'S perceived attraction to Tomo. Ugh.
