Personally I love it when childhood friends get married so this bestfriends to lovers trope is good with me.

This gorgeous pair deserves more episodes though, 4 episodes is simply too short to be a tv show for me. Also, IF a tv show has 4 episodes only, I hope it would get dropped in 1 go. Most people would lose their patience waiting for the new episode, it's like watching a movie over the course of 4 weeks.

So yeah, Soundtrack #1 is a good show, my main issue is just the length of it all.
