yuu(you) is waiting at his classroom for mortis/momo, it's been a bit so he just assumes mortis got lost, after a long while yuu sees his classroom door open, he sees... Mortis!.. Mortis walks over to yuu holding strawberry milk and chocolate milk

"Here! Sorry for taking so long, I got you chocolate milk!"

ah yes, mortis being as friendly as ever, he is yuu's best friend
