Sick love was a common love story in novels. It usually described a person who was extremely inferior or conceited and began to develop strong feelings for another human being for some reason. These emotions may include excessive dependence, possessiveness, jealousy, anger, fear, and paranoia. The feeling of being liked by a sickly girl could be complicated because this person's emotions could be based on extreme injustice and self-centeredness. Sick people may show excessive love, attention, and concern, but at the same time, they may impose restrictions and pressure to ensure that their lover does not leave them. However, this emotion may also bring some benefits, such as allowing the reader to experience the sweetness and bitterness of an extremely unequal relationship and the satisfaction of being deeply loved by someone. However, this kind of plot often involves many problems such as psychological health and moral issues, so you need to be vigilant and pay attention to its potential risks when reading.
