What does it mean to go back to the late twenties?

It really happened, and finally the hairpin on grandma's head is the best proof. Why didn't you make it clear in the end? It goes without saying that Chen Bailin and the hostess like each other, but grandma still wants to go the way she used to go. She still chose her son and family and gave up the impossible feelings. If it weren't for a blood transfusion, she wouldn't be with the role of Chen Bailin. As long as she is injured, her injured skin will age. Who can never get hurt? Do you really think a character like Chen Bailin will love an old lady? Change back to this, the vague ending is more suitable, and leave the beauty to everyone. Or for Chen Bailin, the hostess just knocked on the door and left. He doesn't need to know everything, and he is relatively happy with each other.
