Need Song title from Insert Song of Smile You drama.

In episode 39, during the wedding, they're all dancing, with around 22 mins and 30 seconds in the episode, what song is that?

I would really appreciate it if you could tell me. I know this song is also in Korean and Audition SEA, PH Dance Battle Game because I also played it but forgot the title. It is like MC Mong, Cool, or some other artist that sounds like.
