Help me find this BL!

Okay I can't remember what the name of this one was but it's pretty interesting. Basically there's this.. Company... that's kind of like an escort service?

Anyway one day a old man who was the client of one of the male staff dies and leaves all his money to one of the staff. The police are suspicious and question if he slept with the old man but actually all he did was read books and occasionally hold hhis hand. His secret is his eyes. His eyes are mesmerizing because he has no memories of his past and no passion for the future. They're just like deep pools.

The police or some yakuza finds it unbelievable and threatens him at the top of a building and dangles him over the edge. He's not phased at all.

The commander or yakuza boss is intrigued looking at his eyes, and then pulls him back from the edge and kisses him.

The host dude dude passes out bc he has a fear of body fluids.

We later find out there's like some resemlence to someone in the yakuza boss's past
