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.
