I don't know if it's a long story or a short story, but the story is told from the perspectives of three people.
You ask, is Liu Xiaoyu the heroine? I don't know either. I feel sorry for her the most.
If Liu Xiaoyu wants to accept love, she must first accept herself. Relationships don't mean that if you like me and I like you, we can live happily together. Similarly, two people are not together because they like each other. Does falling in love have to be done at all costs to get the result? Who can guarantee love?
Feelings are the biggest variable.
