Guessing the script for Moving 2 probably focused on characters other than Bongseok?

Seriously, if it weren't for the drama, I bet he wouldn't even have gone to the military.

Kang Full's universe is so massive, they could totally expand the story without Bongseok, focusing on other parts.

Remember how 'The Lighting Shop' had the apartment and Yeongtak appearing? They could connect it to that storyline too.
