I think he was really everywhere at his peak, CFs, interviews, etc. Could be considered some type of Nation's Little Brother(similar to IU) purely because of how popular he was. I think Reply 1988 was a main factor in his popularity but that's a different story ig.
Now I barely see anyone talking about him eye-
I know he enlisted a few months ago, but I didn't see many people talk about that either. I know Encounter with Song Hyekyo was really popular so won't doubt that...but were people even talking about Record Of Youth or was I just sleeping under a rock?
It seems like other actors like Park Seojoon and Kim Soohyun are more popular than Park Bogum these days.
