They're playing a cruel sick game on him and I'm honestly so furious if my theory was true...

I’m honestly so confused by everything I read with this massive update. What’s your theory cause mine is just Jang Gunis the psychiatrist or he just has a lot of dopplegangers and somehow they turned Hyunwoo’s life into some kind of weird test or something. Also like how could the psychiatrist talk to Jihye omg I’m so confused.
