After rereading it. I started to think that Kwon is his life force which is why they have so much sex (I don’t mind it anymore). But the more he becomes “himself” the less he will need to have that much sex since he’s completely back.
I don’t know if that makes sense but after the karaoke and the hospital incident he’s tone it down a bit. If you’ve noticed the things he saying now are from the perspective of someone who doesn’t know how much the world has advanced.
Them having sex right now is completely different because the Shin Yooyoung from the early chapters would’ve pounced on him regardless whereas now…Kwon is the one show made some sort of initiative. I also had this idea the cat had a spirit in it but I think that’s just be being delusional lol
I feel like when shin yooyoung was hit by a car, he actually died and the “him” from his past life has taken control of his body. This is why he wouldn’t respond to his name being called by others or know his social sec number either. And the reason he urged to stay at choi kwons house is because he definitely doesn’t know where his house is.
Though this theory is pretty sad since we lose the real yooyoung who was the first person that wanted to get closer to kwon and genuinely took an interest in him.. I’m hoping this isn’t the case but it seems that it’s leaning to this possibility so let’s wait and see.
