Maybe because Lisa and Oscar were William's parents, they were meant to help each other. Because basically, what they do will someday affect their child's future.
Since Lisa happened to be William's biological mother, and that the boy's biological father was a president director of a large company in Indonesia, that woman should not be reckless. What she does now will someday affect William's good name.
Now Lisa is in trouble with her colleague at work. The woman was accused of plagiarizing someone else's proposal. If she refused to receive help from Oscar, Lisa wasn't sure when the matter would be resolved. She also didn't know what would happen one day if she didn't receive Oscar's help.
Finally, after thinking for a while, Lisa nodded her head.
"I'll give you a hard and soft copy of my proposal tomorrow."
Oscar frowned, "Why not just give it to me now?"
