But won't he die if he act? Or he will die if he became a full time actor?

My thoughts exactly. I feel like I read he would die if he act? He can't act? But I think he said he can act when things calmed down idk

i think it just means him being an idol is first....so if he stops becoming an idol, he will die. idols do acting gigs too so I'm guessing he just can't be a full time actor.
