There was a BL I forgot the name. They were coworkers seme kind of gray blond I think and the seme has glasses.
the seme bought some hole thingy from some sus website which he needed to take some hair and stuffs to link it to the uke. There's also part where the seme tried to find the website but it disappeared.

the co worker one i think, except mc is the one with glasses and not grey or blonde hair....
