When she didn't know who he was, he had fallen in love with her and couldn't forget her.
When she knew who he was, he loved her so much that he would do whatever it took, even if she hated him.
This is just a persistent person, a deep-seated dedication, because he regarded her as the incarnation of love, weaving the dream he chased when he was young into the most beautiful dream, intoxicated in it but unwilling to wake up alone.
Is she just like him?
