Ahah thanks, I'm not a writer xD
I've thought about it while reading the other comments and rethinking about the scene. Nothing related to emotional blocks is ever "simple", and I get the feeling this won't be a lightweight story, so I wouldn't be surprised to see these little metaphors in a form of entertainment (web novels) that's usually lighter/less descriptive (it's not a written text only, so there's little left to imagine compared to a normal novel)

I wonder if the smiley pill is a metaphor for Jaeyoung's happy emotions "fizzling out", consumed by something that drowned them, rather than him being drugged at some point. Could be both as well.
I love Seungmin currently. It's clear he has quite the high affection for Jaeyoung, and I really wonder why and when and how this happened. Could've started from his voice, or as a previous fan of the group. Regardless, I hope the reason and outcome of his feelings won't cause Jaeyoung any further grief and that he can actually help him heal from what happened that drowned his emotions.
