updated with official domestic release date, promo posters and main trailer [domestic cinema channel has less spoilers, whereas this post has almost majorly spoiler, so watch at your own risk]
I believe that some potential/future viewers prefer to bingewatch when the airing ends, rather than waiting to watch 2eps/week, myself included (but thanks to that spoiler of ep4 ending; where my tears come first when I heard the song with the rain scene, world turns upside down... curiosity led me to this)
Yeah I dont think dude is coming back anymore to the lime light:https://e.vnexpress.net/news/life/celebrities/actor-kaneshiro-takeshi-lives-a-reclusive-life-focuses-on-farming-4808463.html
update: Spotify Korea has added the ost album alongside iconic lines/dialogues between main leads as a playlist; check it out by this drama's forum/discussions section of Original Soundtrack Sharing, tqvm
