I've been of the mind that actual sex with Bella is going to be delayed to s3, going by her dialogue in episode 7, and how she's not even comfortable with being in the bedroom with MC right now.
I still think that'll be the case, even with the "I will ravage you later" dress she's wearing in this preview.
Over the last 7 episodes we gradually progressed from stage to stage and I feel like we are finally at that final step where there is just nothing left to do other than finally getting the job done. Seems like the ideal scenario to finish season 2 with a (Bella)bang. Ain't no way Jill is getting touched, so it seems like it's the most logical scene to implement without causing any overall disappointment.
Bella: "It's like I could let go a bit more"
MC: "I could tell. You don't have to hold anything back with me. But, of course, we're moving slowly."
Bella: "We'll see..."
(She's already succumbing )
MC: "Oh? Don't tease me like that. I can't handle it if you do."
Bella: "If that's already a problem..."
Bella: "You definitely couldn't handle me when all stops are pulled out..."
