Hashiba said "I was trying so hard to catch him" dude what did you expect from him after what you did to him ?

Ah thanks for explaining, I did not understand. Kei said something that he heard a rumour from ono-san that the boss had a guy partner but then found another one and killed the previous one so I thought that the boss wanted Kei dead and Hashiba 'saved' him by lying that he had killed him but actually selling him to Ono-san but ok no I was ded wrong it seems.
Kei is at the center of Hashiba's desire, which is why Hashiba lied to Takahashi that Kei was cheating on him. This is what caused Kei to be sold to Ono as a sex slave, in the hopes that Kei would turn to Hashiba. However, Kei already knew what was going on, and so was prepared to suffer endless humiliations in order to escape. This is why Hashiba did not fufill his desire of getting Kei.
It is a good ending, especially since Kei gets to be happy with Junta. However, it is slightly bitter because the lie that caused all of this stupidity was never exposed. No wonder the good die young.
