Thisss, honestly I think people are leaning too much oh the professor sees garam like the manager, which is not true!!
I’m gonna post this cause my friend tofu has an understanding of what this white figure is” As the story progresses we can see the manager figure as heejae's self hatred. Because it WILL show up everytime heejae doubts himself or feels anxious about his relationship with garam.”
Omggg yessss............esp whenever he's at almost Peace...........guilt is tripping him over with undeserveness like state and the fear of missing out a truly understanding one....................more importantly........(only my guess) the faces might not be same or anything.......just the understanding the prof part is what makes the ex-manager making him look like he exact copy of garam

I don’t understand the Kim hate tbh.
His ex manager died due to a fire. We don’t know exactly what happened yet but not everyone handles grief the same. The author is doing an amazing job portraying what it’s like to feel remorse, guilt, shame, etc. This isn’t your typical “oh I have to ask for forgiveness now or else I’ll regret it.” He’s already dead… that just complicates things more and he’s going nuts trying to find out what to do. He already knows he was in the wrong, all he can do is forgive himself and learn from his mistakes.
