Resolved [BL] world hopping, 1st arc MC was (rather old) male prostitute

I try to find with the tags with no success, I completely forget the title

in this QT novel, the first arc was male prostitude, drug addict. ML was some kind of grey business boss. Somehow (I can’t remember why) this ML locked MC and order his subordinates to torture him. MC was saved because the system made him recite poem/love letter from ML late bf (or white monlight, not sure)
The first arc ended with MC saved ML and counless other, sacrificed himself driving away a car installed with tickling bomb.

arc two, seems it was a prison life. I hadn’t read yet since I planned to wait for more chapters before continue… at the end, now I cannot remember the title.
Anyone please help me.
Thank you

 

I'm almost dead

 

Is it HE or BE?

 

Arc ending is kinda BE but not much. It's on hiatus now, haven't been updated.

 

Thank you!!
Uh, it’s on hiatus? Sighhhhh

 

Is it like Heroic Death System? Where the arcs are BE but the story is HE?
