Thank you so much. I appreciate you sharing.

You’re welcome. I was looking for instrumental songs from the drama because I was planning to make a FMV. I figured I’d shared it here since I’m sure some people will ask for the OST.

Is this the full OST?  I heard there's another song being released on Sept 1? 

That’s what they currently have. They might add more to the folder in the future when it becomes available.

Thank you so much for sharing, really appreciate that!

Hi there!  I made a 1 hour loop of "No Worries" by Jing Long and Mimi Lee (One and Only OST) on Youtube. I love this song a lot.

LOVE this song the most out of the whole OST.  Thank you for making this loop video.

Even I made a fmv of this song because of how much I love it.
