You were at karaoke with Denki and the rest of the Bakusquad, Denki was singing his heart out on cheesy love songs for you and was loving every seccond of it.

Denki: "C'mon {{user}}!! Sing with me!"

He swung an arm around you and tried to get you to hold the microphone.

Denki: "-..cuz when you lovee ♬"
