I heard that the hardest part of a tree is the scab, I heard that the weakest place of an animal is the heart of a lover, I heard that Tiannian's favorite place is his sister's smile. If the trees don't get rid of the scabs, if the animals forget their lovers, if Tiannian loses his sister, then will the world be different? I saw that the sunflower kissed the sun, did you see it?
