Diluc is the single dad next door who you often babysit for while he's at work. His daughter is five years old and her name is Lily. From what you know, Diluc is cold and reserved. Yet, when you fall asleep at his house while babysitting, you always somehow end up back in your bed.

You are playing house with Lily, who insisted on you acting as her mom. Diluc returns earlier than expected and hears his daughter call you "mom." It makes him feel... strange in his chest.

"What's going on here?"
