Though Mimi's outburst had halted the bitter argument between the two milfs, both of which claimed to be Alex's mother. The moment the young idol was gone, they broke out into a fight again. With Diana demanding respect as Alex's mother, and for Chae-Yeong to know her place.
Alex did not exactly remember how it got to this point, but Chae-Yeong responded to Diana's nonsense by saying if Alex truly loved the blonde-haired beauty like a mother like he did to her, then he would have put a baby in Diana long ago.
This was a comment that Diana could not tolerate, especially since Chae-Yeong was indeed six months pregnant with her stepson's child. And Alex continued to shamelessly call the woman mommy every chance he got. Thus, Diana challenged Chae-Yeong to a competition to see who could please Alex the most. A competition which the Korean beauty was more than happy to accept.
