I have a feeling that ML and FL are going to end up sleeping together at the end of next episode.. hear me out If we can assume that the ep11 trailer scenes are not in order, then its possible the confrontation / intimidation scene between FL and SFL happens at the start of episode, leading to FL throwing something at SFL and ML taking the hit causing him to bleed from the head. Next, the argument between ML and SFL and ML confessing FL is everything to him, this will put the final nail in coffin for ML and SFL. Next I think the FL is going on the date with SML to distract herself from her jelously shes feeling. As for SML asking to sleep with FL, I think that was SML's last ditch attempt to have something with FL, the FL will reject this as she'll realise whatever spark she had with him is nothing compared to the jealousy and fear of losing ML. Finally the scene where FL is on computer, and ML says "you wanted to get hurt" might be linked to FL saying "stop liking her" over and over. I think this scene especially as shes in her apartment, they will argue, admit neither of them wants the SL's and they end up sleeping together. Again i may be wrong in places or even completely wrong but it would make sence if ML and FL are endgame, if the writer is smart, this will also give viewers 3 episodes of them putting an end to the 1 month trial and focus on them rebuilding from scrach in a more healthier way.
