The phrase "I wish you happiness" was usually interpreted as a kind of blessing and wish that the other party could live a good and happy life. However, if there is another sentence hidden behind this sentence,"I love you, will you come back to me?" The situation was more complicated. This kind of situation often appeared in novels, usually hinting at the protagonist's feelings for the heroine. The heroine may say this when she says goodbye, but in fact, her real thoughts are "I love you, can you come back to me?" She hoped that the male lead would realize her love and feelings for her and return to his side to be with him. This situation could also happen in real life. If a person loves you, he may say this sentence when saying goodbye, but in fact, his true thoughts are "I love you, can you come back to me?". If you encounter such a situation, you need to think about the other party's true thoughts and make your own decisions.
