Him being clingy and flirty that way seems like his way of something like a theraphy, which evokes the lost emotions of mc. He's helping him that way too. And just a little detail again, I noticed that blondie member's face is covered again. It's like mc's mind deliberately forgotten him, and when he tried to recall who the "hyung" he's talking to from what happened in the incident, he couldn't even remember. I could even guess he actually couldn't remember Blondie's face atp. That sus guy definitely did something.
I HATE people who mock and hate artists for taking breaks because they are sick. I wish y'all get sick instead and never recover.
