There are almost no hyyh references but a lot of v and Jimin references.
This is from taes vid
See.
Looky here another reference.
This is the painting from LIE
This is from the ink blot test scene in LIE
Ok so I think that hobi is faking his insanity. He wants to get away from Jimin and stop thinking about him. So he does so with the pills. But he can't get Jimin out.
So he assumes he's insane and takes the pills and it's not working.
Hobi and V are together. That means hobi is tae's demon but Jimin is connected to Hoseok
