Lovers - Pinkwave, but it's a Pink Impostor and Lime cover
A cover of Pinkwave from FNF VS Impostor V4, featuring Pink Impostor and Lime! This is set in the past, which you can tell by the fact that Lime hasn't got a headset.
Fun fact: Lime's headphones were a Valentine's Day gift from Pink Impostor, about 5 days after the events of this cover.
