Help me please.!!

Ah.. I can't believe I forget this yaoi's name.. Anyways. The seme is a captain of the boat. The uke was just a waiter. So this and that happens and they two ended up having sex and the uke thinks that he used his pheromones to have sex with the seme and the seme somehow forgot what happened or maybe he just forgot the uke's face. Fast forward to many years the uke is a...person who finds the correct person to marry for their clients and the seme is one of the uke's client... I'm too tired to write the rest but I hope someone knows this!!
