PLEASE, help me figure out the title of this yaoi! It's driving me crazy

So this high schooler is kidnapped (or maybe sold) because his relative owes money. The yakuza or whatever take him in, and decide to train him to be an adult video star. That way they can get some money from him.

The seme trains this uke in sexuals for a month, and they start developing feelings for each other.
Then the seme's boss directs him to kill the uke, since they don't need him anymore/he's a liability.

then

the uke gets upset and the seme can't bring himself to kill the uke. Later on, uke and seme are working in the industry together.

Shinjuku lucky hole
