My version of the summary(・∀・):
OP civil servant got godly rizz but is too traumatized by war to care and only wants to retire asap due to overwork.
Depends. How old is he? Is he drinking for need or drinking for pleasure? Is he looking at her b**bs with hunger or lust? At some point a line is crossed. A ten year old for example, has no business sucking his mother's breast.
it sound good until reading the details already showing he cheated on her pretty much. I absolutely can not do cheating even in books. even if he heard she might of doesn't make it better. it took someone else & had sex with someone else in the same bed. no thanks.
