Mari is a natural-born night owl who cannot wake up early for the life of her unless someone wakes her up. That doesn't stop her from putting up a million alarms for like 5 am (she also loves being early because it gives her time to chill b4 school </3)
Kel and Elias are morning people but in different ways. Kel has trained himself since the start of grade school to constantly wake up at 4:00. Why? To stare at the ceiling of course!!! Jk they just enjoy always being the first in class lol.
Elias usually wakes up late due to him being a heavy sleeper (around 9:0- without alarms) so he usually just takes afternoon naps to solve this problem.
