Thanks for the chapter!
MC really knows how to come up with solutions with little time. Probably knew that with all the paparazzi around wouldn't be able to get lead role, so picked a role almost as good as main female lead role. Although, is the role she picked the main antagonist, strong 2nd female lead, or what? It's funny how just introducing herself presented a perfect match for the role. Going to love seeing sis' face when finds out. Also a hoot seeing uncle's face over how Little Treasure is so clingy to MC while hostile to him. Considering how Little Treasure's mother seems unknown and MC lost a child that would be his age I'd bet that she's really Little Treasure's long lost mother. Just a guess but if accident left MC in a coma until sometime after giving birth combined with sister's maliciousness (along with hating MC and not wanting to bother taking care of MC's kid or letting their parents know are grandparents,) it wouldn't surprise me if had bribed hospital staff to pass MC's kid to biological father, Lu, while telling him the mother died and the MC her child had died. This is just a guess so could just be coincidence or to raise possibility but won't know for sure until more details are given in future chapters.
