A guy like you
I'm not sure but it sounds like http://www.mangago.zone/read-manga/trace_of_you/
This description also kinda sounds like "Paid", since the uke did get into an accident and lost his memories. He also has a black-haired (childhood) friend with glasses. The only difference is that the uke is the blond one in this manhwa and the seme has dark hair.
