I swear this manhwa was called dear stranger, but when I search it, something else comes up.
It was an omegaverse BL, this masculine looking omega wakes up from a coma without his memories, and an alpha who's more on the prettier side claims to be his husband. Turns out this guy was a piece of shit before losing his memories and he hosted a cooking show or something. Anyway, he started developing feelings for the alpha but one night, the alpha gave him divorce papers and he lost his shit.
