The Third-Gen Chaebol Becomes a Genius Actor재벌 3세 천재 배우가 되었다

Regarding the MC, the previous body owner seem to have more personality than the MC even while being an asshole, as the story goes on he just seems like the typical cool generic MC.

The AI system becomes useless after the first introduction, the whole memory synchronisation started out interesting with even the mystery behind the mother's death, but the whole vomiting blood everytime he gains bits of memory or starts to have an episode was annoying, it's like the author doesn't know how to write about trauma so he just sticks with vomiting blood without having any medical problems miraculously.
