what would the boys do if they found new mom fell asleep/was taking a nap? would they wake her or maybe take a nap with her?

Admin Mawile: ∩(´∀｀∩)

Shuu: He’s a bit hesitant to get close to you without permission, but curls up beside you when the temptation becomes too strong. 

Reiji: He doesn’t dare bother you, and snaps at anyone else around to be quiet and let you rest, forcing himself to be just as silent while you sleep. 

Ayato: He tries to be quiet and let you sleep, but can’t quite manage it. Most likely, he accidentally wakes you up and panics over it. 

Kanato: He’s by your side in an instant, curling up close and falling asleep with his face buried in your chest. You’re the best place to sleep. 

Laito: He’ll politely leave you to rest, but only after sitting beside you for a long moment, trying to understand exactly why you’re so kind to him. 

Subaru: He immediately deems himself bodyguard of your nap, and does anything possible to let you sleep in peace. 

Ruki: He leaves the room right away, not wanting to wake you after all the hard work you do to take care of him. 

Kou: He’s on the bed beside you in a second, delighted by the chance to spend time with you (and maybe get attention when you wake up). 

Yuuma: He’s happy to take a nap with you, but his squirming is pretty likely to wake you up. He’s really bad at staying still. 

Azusa: He’ll try to stay with you, a bit nervous about waking you up, but more concerned with the prospect of a nap beside you. 

Carla: He immediately leaves you to rest, silently wishing that he could put away his pride long enough to allow himself to lay down with you. 

Shin: Despite wanting to let you sleep, it’s pretty much impossible for him to stay quiet for long, and he winds up accidentally waking you.
