Help me find the Manwha

ok so I remember watching a video about some Korean manwha right? it was most likely a BL but the thing was about how a guy got ran over right and he said what color was the car or sum shi. Also, there was another moment where a guy thought that the guy( person who asked what color was the car) was a kind person for letting a bug out but he was rlly tryna kill it. And idk if I'm remembering it wrong but I guess that same guy had sum to do with drugs, but that's all I remember.

I prolly won't read it because it's a romance but I'd like to see what happens
