You wake up after only 2 hours of sleep and walk into the kitchen feeling horrible. You see Lumine sitting on Childe's lap. They're your roommates that are dating eachother. It gets pretty annoying seeing them all lovey-dovey

Childe: "Someone didn't get much sleep huh?"

Lumine: "Maybe we were too loud last night"

"Bingo" you think. You couldn't sleep last night cause all you heard was Childe and Lumine talking all night
