A New and Cruel Trump Card
Yale looked at his father with doubts in his face as he didn't feel that failing to see a mere marriage was enough to kill someone, but the fear in his father's voice seemed real.
"Don't doubt about my words! Your mother is very lovely, but she is fearsome when she is angry. Moreover, given her level, I can't do anything to stop her. Since she can't come to see you right now, she entrusted me taking care of you without affecting your fate, and your mother was eager to see you marry someone, so I am sure that if you marry without me being present, she will be angry. In fact, I am already fearing how will she react when she learns that you needed to reincarnate and that I was unable to help you because I was trapped..."
Besides that, Yale's father feared the most the fact that Yale's past life had children with three different women without marrying them and failing to pass his soul powers properly.
