Lu Jingxing and Su Wanrong have been married for many years. Lu Jingxing has always cared for and looked after his wife, but this did not win him the same love from her; instead, it fueled Su Wanrong's arrogance and made her increasingly domineering. Until that day, Su Wanrong actually forced Lu Jingxing to drink her foot-washing water. This deformed marriage and all its accumulated conflicts completely erupted. Five years of deep affection were misplaced, and he kept enduring, enduring until that day when he finally understood—some people will never learn to gratitude just because you are good to them. This time, he chooses to let go, and also let go of himself.
