Su Wan lives alone outside, and always maintains rationality and restraint in the face of long-term innuendo and malicious ridicule from her neighbors. Instead of getting into a quarrel, she chose to decorate the insulation wall in a legal and reasonable way to protect her living space. Faced with the other party's unreasonable entanglement, she calmly collected evidence and bravely defended her rights, ultimately letting the selfish person bear the consequences. This experience made her understand that kindness must have a bottom line, and gentleness is more powerful. As long as you stick to your principles, respect yourself and love yourself, you can keep your own warmth and peace and live an independent and calm life.
