What about when Jiwon gets old and eventually passes away? I kinda wanted to see how the author would handle that. If Jiwon would be made into a vampire or if they would go for a Lovers Doll type of ending (which had an S-tier ending, even if the art was kinda mid).
The extra chapters were good, but I wish we had gotten a scene with Sungjin. It feels like he didn't get any form of closure, while the other three on the boat did, and he deserved closure as well...
