there was an arc where the original owner was deceived by the family friend who only wanted his families money after his parents died. The father and child of the family friend used him and then stole of his property and even killed his dad by messing with the car ro ensure he died. The family friend child was the one to do all of this and the original owner used to date him.
Sounds a bit like Pleasing Start-Over Arc 6 IIRC original owner used to date this actor who was signed to an entertainment company his dad had shares in. The actor killed the dad by tampering with the dad's car, and cheated the original owner to sign over all the shares he inherited.
