To pursue the path of cultivation, one must first understand one's own heart.
Yet the human heart is inscrutable, even to oneself, there will always be moments of wavering, thus cultivators often introspect.
Not deceiving oneself is the foundation of a seeker's quest for the Dao.
However, sometimes when one cannot see through the fog within their heart, they fall into confusion, not knowing what they are thinking, this was the state of Lin Yu's heart before.
But after the song, she had an epiphany.
When all is said and done, she was merely jealous.
Originally, Lin Yun only fancied her, and now there was the Flower Fairy too, she was jealous.
Because Lin Yun wanted to spend time with the Flower Fairy, he asked her to leave, she was angry, deep down, it was still jealousy.
