I agree with the general idea of smoking as a proxy for an unhealthy but addictive relationship, and I also thought he was throwing a pack of cigs away to represent a new start. But if you go back and compare the cigs, either Haesoo’s (red on top) or Joowon’s (pink band) it doesn’t match. I think he’s tossing that infamous lighter, which is all blue. Still a fresh start, getting rid of the detritus of yesterday, with a more satisfying ka- klang sound. (I’m pretty sure author likes us to examine all these juicy little details.)
Yeah, Taku’s lighter, the one that pained Joowon to find on the floor of his car when HxT were making out. I saw a comment on here at some point that it was the lighter, so I looked back at the 3 things, and it would appear to actually be the lighter. Which surprised me, but then I thought back to when this chapter dropped there was still a little suspense as to whom he’d end up with, if anyone.
For some reason, I thought he didn’t take it back as another way he could ingratiate himself to H, but I don’t think that actually happened. It is strange, though, for a soft pack of cigs to make that CLANG sound. It could be intentionally vague to drive speculation at the time chapter was released? Anyhow, I definitely felt anxious for Joowon at this stage of the story.
Haesoo quitting smoking as seen in this chapter where he tosses his pack of cigarettes is very symbolic!!
Here’s a really great thread I found on the meaning of his smoking habit, and how its connected with his relationship to Joowon: https://twitter.com/joohaes/status/1340598549944287232?s=21
