What buildup ?

.
Before episode 9 MC and Elena barely spoke with each other, than bumm, in the beginning of Episode 9 MC and Elena are like BFF because of their shared love for one of the "minigame" . . .
and then they start to interact. in that episode, oh yeah there was a moment in episode 8 too, during the dorm party, Honestly it's more memorable to me as MC dance with Josy and Elena mentioned it's look like love between them.
anyway, than ep 10 JB comes at you as the Cuck he is and almost begs you to fuck his girlfriend, in front of him, and then Elena text you , basically apologizing for his behaviour , and in the very next episode you take part in their sexual act.
I would hardly call this as an "
Insane buildup " , considering that for example , getting together with Jill and having sex with her , took you as long as to reach the end of season 1, what is 8 full episode.
