The ml already knew the mc from many years, and saw that mc father was a cheater, but to protect mc he never told. Then one day mc and ml entered in a room where the affair was going so mc was shocked and mad, but then he noticed ml didn't seems too much surprised so he understood that he knew it already and didn't told him. The mc hurt run away but have an accident when he lose his memory. So in the present mc's mother and ml are still in touch to take care of mc. Like in one of the next chapter in ml phone will arrive a message "how's he?"
"Don't hide things from me" "OK!"
