Guys to sort the confusion. This story was a short story part of an event with short story collection by other authors. So yes this was completed with 16 chapters. But due to popularity and being loved by fans, it was announced in July 2024 it will have side stories with 16 chapters in total as well releasing in spring. Today the author posted an illustration with the captain 3월 22일! meaning the side stories will release March 22nd 2025. So the main story is complete and did end with a cliffhanger. But luckily we're getting it continued with a side story. Hope that helps♡
So basically he wants someone to love/like in all his all, the real horrible him. He likes to hurt what he "loves" and desire as it the only thing that thrills him. What i don't get is way he kept an eye on Dajeong after him and his mother left them. What desire did he have there to do that for 12years(?).
