obsessed with the trope of person a can't sleep unless person b is in the same room with them. they don't even have to Sleep Together or anything – person b could literally be cooking or gaming or showering or whatever but it's enough for person a to feel safe to finally rest their eyes. plus points for when person b doesn't notice that they've dozed off but when they finally do, they just look at them with the softest fucking eyes before tucking them in. maybe they'll even.... give their beloved a small kiss on their forehead.... ok more plus points if this isn't an established relationship!!!!!!
