SEEART has revealed the MV to their pre-release song "Cup Cake"!
The MV is actually not a music video but rather what they're calling a 'music photo'. It uses a technique called cinemagraphs where a still photo is combined with a moving video. The song itself features Phantom's Hanhae, and it's a sweet song that sings of a girl's love.
