Surprised there's not a 'translator's note' but i assume 'cookie vid' just means like post credits, which "Marine" (Marvel) usually does (i guess it makes sense with context like a 'dessert'/bonus, but still)
This feels like barely MTL
ManhwaFreak has an alternate translation too, and it is based on a webnovel tho idk how accurate that is (tho the website i found that did a translation randomly censored stuff like 'suicide' and 'nipple' even tho in the context wasn't anything too extreme)
