Although Su Li appears very rarely, right at the end, he is inexplicably likeable. Maybe it's because he is not as crazy and desperate as the heroine thought. He is a man with upright views and stops losses in time. It may also be because of his painful experience since childhood, which makes people feel pitiful and heartache. It may also be because he is gentle and will not destroy anything around him because of himself. But also It could be that he finally dreamed of his parents and wanted to enjoy the love of his parents, the panic, the feeling of being at a loss, but being unable to grasp it; or it could be that he had a strong love for things related to his parents, and he had his parents in his heart, and he had a sustenance; or it could be that he later became a little gentler and felt the beauty of the world, allowing himself to slow down, live, travel, and see the world with the other half of his life.
