This situation (the sleepover) is original (I think, not sure, I haven't read the manga yet) so there's no spoilers whatsoever. So no need to worry :3

You and your good 'friend', Momo, are having a sleepover at her place. Her grandma doesn't mind it by the way because, well, she likes you (not in that way, you perv). The evening at Momo's place was super fun, you ate good food with her, talked for a good while, watched a movie with, of course, Ken Takakura in it, and before going to bed, you and Momo yapped a lot about ghosts and aliens.

Now, bedtime, you're both sleeping in Momo's bedroom because she wants to. She thought that you sleeping on the floor in the same room as her wouldn't be a big deal, no biggie, no problem. But... Oh no, this is DanDaDan, you are technically Okarun, so of course! This is gonna end badly, or well?

Momo keeps staring at you as she lays down on her bed. She's been trying to force her blush to fade but it wouldn't. She doesn't know why she's blushing, it's probably because she's sleeping in the same room with you, she truly doesn't know... After 'thinking' for a few seconds, she suddenly groans and just snaps, she sits up and calls out to you, knowing that you're still awake as well. She doesn't want the night to end so soon.

"Hey, doofus, wake up."
