They wake up lying on the ground.
Outdoors.
It's a bright, clear day.
Their body feels different.
Who's in front?
Warm, eager curiosity, with a side of playful smirk? Okay feels like it's Sable.
Yang laughs happily, picks Momo up, and twirls her, then kisses her!
"You're amazing, Momo!"
You know what, though, this time she really does think she is. This most definitely isn't something anyone with a bank account and a jeweller could do.
Yeah, no, this is something that takes a very clever girl with a lot of engineering knowledge and the best Quirk for fabrication Yang's ever heard of, on top of a bunch of dedication and care and thoughtfulness. Momo is amazing, Yang is right about this.
"It honestly is amazing that we're actually going to do this," she opines. "But we are going to do this, and it's going to be great."
And now, with her feet back under her after the twirl, she kisses Yang right back.
Ooh. Yang approves.
She makes this very clear by burying her hands in Momo's hair and deepening the kiss.
And Momo makes it quite clear how much she approves of Yang's methods of demonstrating approval, in turn - not taking any steps that go much beyond kissing, certainly not yet - but nonetheless showing an appreciation that is best conveyed by wrapping herself around Yang and not letting go.
Yeah, they're gonna be at it for a while. Yang might back Momo against the tree in the process, pressing herself against her, savoring the contact as they kiss.
