it's been so long but I finally found it
I kid you not, i binge read it and i'm obsessed
yay I'm glad you enjoy it! if you're into dark obsession vibes like that, one of the short stories series that been on front page lately is actually made by the same author!
I knew it felt familiar, but I didn't realize until now only found this one cuz of a random twitter twt
It was a recent manwha a few months ago I think, the top had blue hair and bottom has brown? MC is the bottom, one day his new boss shows up to work and it's the top, he's a freak and kind of crazy -- he constantly trying to get along with the bottom, trying to get him to move in with him, put plants around the office cuz why not... it reveal later that they used to be friends in highschool
