Review Detail of TackcaT in Everyone in the Qin Family Pampers Me

the first chapter is a bit confusing. I've never heard of someone adopting an 18 year old, or letting said child decide on if she wanted to be adopted. it's almost as if she is the one in charge. also, the country gave her a body guard? I love the humor in the book though. the ml is pretending to be her teacher and actually tells her he is her future husband lol. I'm wondering is she is a Cyborg!
