Who sings this Korean song?

It starts off with the piano. The rapper sounds like Outsider. He
starts off with: This right here, for my baby. My love, that's true. A
girl sings the chorus: Love is you, so tell me what is love. na neul
saranghae. (more korean) Your love, your feel, your heart. Then he
raps: I know it, i know it etc.

The song is in a happy beat.
