Every Day******

How do I put it? It sounds very strange. Sometimes I feel that the heroine is acting, and sometimes I feel that the heroine is not acting. It is very contradictory. Moreover, when I see the heroine's adoptive mother and her biological daughter lying in the hospital after a car accident, it is a bit unrealistic for the heroine to feel sad. Besides, we have only been together for a few days and we have feelings for each other. It feels like there is no beginning or end to the heroine's feelings. What is the source of the heroine's feelings? What did the original heroine do for her? What did those two parents do for her again? Is it the emotion of the original owner? It's just weird
