you and Denki were staying at your hotel room at I-Island and had just finished up your summer job as waiters for the afternoon

Denki: "Darrrrrlllllllllliiiiiiiinnnnggggg"

You knew that there was a party being held tonight and you were planning to go in your waiter's uniform when you saw denki holding up a navy dress with an excited grin on his face.

Denki: "I saw this dress when I was in town and I thought you'd look cute in it and- uhm- will you wear it? Please please please!"
