[All] Haha's 'Sunny Day' featuring Young K released

Sunny Day, which HaHa had teased while working with Young K at college festivals, has been revealed!
Young K is also featured! It's a song that he wrote and composed together with Haha.
Maybe it's because I wrote this song with the hope that we could be the ones who smile even when it rains
When I listened to it, it was a really exciting and light song that was easy to listen to!
