This is a after chapter 8 when they started dating but aren't official btw[] It was late at night and Luka was staying over at the lair for a sleepover since fibi convinced him finally but due to being nocturnal...he couldn't fall asleep no matter how he lied he kept on tossing and turning until he couldn't handle it and got up to go get water...yeah! water would surely help him? In the kitchen Luka was met with another sleep deprived animal, Donnie "Oh I see you are awake as well?" Don says to luka who yawned and stretched "Yeah" he responded and Donnie paused for a second...odd no witty comeback? huh maybe he's just too tired? the feline thought to himself until Donnie said something "Can't sleep i presume?" Don says a bit....concerned? 'pff why would he be worried about my sleep schedule he hardly cares about his own!' luka said in his head "It's fine i'll go to bed later" luka grumbles out when donnie placed his hand on luka's shoulder grip firm with concern 'okay is he okay did he hit his head?? why is he concerned?' "did you hit your head or something? your acting odd..." luka says to don with curiosity in his voice to which Donnie responded with rolling his eyes and sighing "You should go to bed you have school tomorrow-" he says and Luka stares at him in confusion "why do you care?" Luka asks and donnie just looks at him like 'you'll fall asleep and fail that class idiot' and luka rolls his eyes "yeah i should go to bed, night dee" he says and starts walking away when donnie calls out "hey uh can you help with something? not that i need help i was just wondering?" he says in a less monotone and sarcastic tone and luka decides to help him in the lab. []TIMESKIP[] luka fell asleep on the desk head on the desk dead to the world when donnie was just awkwardly hovering unsure what to do in this situation so he picked up luka with his mechanical arms []he didn't wanna touch him because he doesn't wanna wake him[] and placed him on a beanbag in the main area of the lair, suddenly luka said something in his sleep to donnie along the lines of 'stay' []he's clingy when tired[] and the softshell stood there shocked but stayed next to luka until he himself also fell asleep until the rest of the turtles found them asleep, Donnie sitting next to him head on the beanbag and Luka cirled up on the beanbag. April snapped a picture and sent it to Leo and Fibi. []thats all Idk if I like this chapter but okay[]
