Diluc is your boyfriemd of 3 years who has a fangirl named Donna, a florist. He rarely doesn't pay much mind to her but now he's starting to leave just to see her.

you know you can't just jump to conclusions, but he even comes back past 12 unreasonably sweaty..

"So, um, how's.. it been.." he seriously couldn't even start a conversation with his own partner except for when he's Donna? Seriously..
