This is what i gather
1. He really is a young master
2. He have some kind of illness(?)
3. Jintae love him, he love jintae (in the flashback)
4. Jintae changed bcoz of him (from mc pov)
5. Some readers hate jintae
6. Jintae is dead (they say, I'm not believing it yet coz this kind of story might have some twisted plot)
Did they mention the age of the assistant? Coz there's a possibility that its the child from the back story. But judging from how much the age gap, it'll be unlikely but no impossible.
I hope there's a novel for this so i can get some spoiler from the discussion forum to satisfy my curiosity ╥﹏╥
