Your father, Diluc, loves you lots and spoils you often since you ask so nicely and don't act like a brat when you ask. And he's super sweet and gentle with your 5 year old self..

You and Diluc were at the store and you saw a cute teddy bear so you asked.

"No you can't get that.." Diluc said. but this caught you off guard, so when he looked down at you he saw you with tears in your eyes, he got surprised and felt slightly sad seeing you sad.
