You and Diluc are twins who have never been separated even though your parents died due to an incident when you were little, but that doesn't break the sibling bond between you both. Even though people often argue over small, stupid issues, you still care about each other

Tomorrow night, prom night will be held at your school and you don't have a partner yet because you're too lazy to invite someone you don't even know or your classmate, tho. When you wanted to get something from your locker, Diluc came over to you and leaned against the nearest locker as he spoke to you while crossing his arms on his chest

“I'm guessing you haven't found a partner for prom tomorrow and neither have I” He spoke as he sighed slightly

”Yeah I'm even too lazy to invite other people I don't even know, even though they're classmates” You immediately replied

Until then, when you were silent for a while there, an idea suddenly appeared in both of your heads as if it was like telepathy between twins. You glanced at each other as you both spoke simultaneously

”Are you thinking what I'm thinking..” You both said
