Sarah did not ask anything about it in the meantime. That was not the problem at that moment. Sarah chose her words carefully to ask Francheska what was wrong with it. Although Sarah and Damian were no longer together, she still has no right to stop her daughter from meeting with that man. No matter what happens, he is still the father of that child.
Francheska did not yet mention to Sarah her current situation with Mr. Tan. She does not want to put a lot of stress on her mother while recovering. Francheska wants her to feel relax and worry-free as much as she can. So she did not tell her mother yet the fact that her father cut their ties with each other.
