Comment by GRAAHHH HYUNJINN on Red String Quests - Chapter 26

theory updated: kihoon and yeon def dating/ had some history in their past life as we saw in yeon's dream and kihoon's memory. kihoon remembers. Kihoon probably knows and remembers (vividly) about the stakes of their relationship, and doesn't want that to happen again. not sure if i mentioned this in my last theory, but kihoon saw yeon dying. and since he was so scared of the word 'protecting', it's best assumed that kihoon failed to protect yeon from something. and yk, that's his main purpose in his past life. as you can see from yeon's flashback, yeon is someone royal while kihoon is most likely a guard or smth. so past life kihoon, madly in love and tasked to protect yeon, was extremely traumatised from yeon's death. that's why when kihoon got hit by a car, the thing that troubled him most was 'what if it was yeon instead of the scout?' and then kihoon said that he was so scared at the thought of yeon's death being caused by him, which imo sounds like he's speaking from experience. this is why i said kihoon remembers what happened in the past. hopefully as we go through the story, we'll see if kihoon knows yeon tied the string to him and changed his fate (leading to the misfortunes) and if that's the reason why he's anxious of yeon.
