two guys in a class project start hooking up even though one is a jerk & straight and the other is a nice gay guy. the jerk eventually realizes he is gay for the nice guy and thats where s1 ended, with him literally running away from the rainbow.
there's also an annoying guy who toyed with the gay mc in the past and led him on only to date women. he comes back this season... hope he gets a fist to the face tho!
i think its worth the re-read even tho the art changes.. hope that helps!

I don't really remember the s1 story but I don't want to reread and get attached to the old art style ╥﹏╥
