SEKAI NO OWARI's Nakajin will release his fourth solo single "See U Soon" on May 15.

The track is a collaboration with Los Angeles-based producer and songwriter Skylar Mones, who has worked on Grammy-winning projects for artists including Rihanna and Dua Lipa, along with songwriter Elle Vee.

"See U Soon" centers on a push-and-pull relationship, capturing the strong, almost unexplainable attraction between two people. The jacket artwork is based on the concept of "lovers reuniting inside a game."
