It's about the messy human nature that grows in the corners of a bright society where the sun doesn't shine. Being judged, hurt, harboring grudges, conspiracies, and grudges, it is always difficult for people to escape from the grief of the past, and they are always brooding about those who were judged and abandoned them.
We love each other, but we are still greedy; we talk about love and love, but when it comes to grudges, reason always trumps emotion?
