Here is a fanmade video with K. Will’s Thank U as Warm and Cozy OST Part 1. It is an upbeat song which you could have heard in the sunrise scene as Baek Geun Woo and Lee Jeong Joo goes up the viewing deck.
If you ever wonder what’s the background song of Yoo Yeon Seok and Kang Sora’s Dongdaemun scene, we got the answer for you. The song is titled “Butterfly”, sung by 하늘해 (Ha Neul Hae) & 공보경 (Kong Bo Kyung). The song graces Warm and Cozy OST part 2.
It’s a soothing song, isn’t it?
