Anyone know the title of the song that plays at the end of the episodes? 

It's written in ending credits that it's Dive by Jung Jin Woo but I think the ost wasn't released yet

They will release it tomortow. Nice ost

Kinda sounds like Sungjae's voice - but I could be wrong

 Lovelyy:

They will release it tomortow. Nice ost

Any idea where it will be released? Searched on Spotify and Prime Music but couldn't find it.

- The 1st ending song (episode 1-3) is Dive by Jung Jin Woo. It was released yesterday. You can find it on the JTBC Drama YouTube channel.

- The 2nd ending song (episode 4) is still unreleased. But I can hear Yook Sungjae's voice.
