Kidok

I can't remember much but it had an unemotional mc who didn't cry often and for one of the scenes, he sees water droplets on his arm and thinks it's raining and looks up but sees it's not, and he's just crying. If you recognize this scene please say where it's from!

I saw a photo of this manhwa a little while ago and I can't find where it's from If you know where it's from please say so!
Also sorry about the photo I know its a little weird
