디어 마이 에디터

The protagonist is an editor for the adult video introduction channel [Pumbeonking]!
Due to COVID, he spends his youthful freshman year entirely on editing and gaming.
A year passes, and spring arrives when he turns 21.
In front of him appears the most beautiful girl in the department, but he's become a used secondhand freshman?!
"Hey! Wait a minute!"
Her identity feels suspiciously familiar!
