Revenge or Betrayal or VENGEANCE

Meh but looks somewhat interesting

I’m at 38 (6.7.24)
The ml’s step sis and her husband betrayed him and stole from him, their son who was always in love with ml, and who’s schooling was paid by ml, wanted to pay ml back all the money his parents stole, so he starts working for ml.
It’s also a reluctant love story because ml struggling to see the guy as more than his nephew, but that doesn’t stop the guy from doggedly trying… and succeeding.
