There were many reasons for Tian Xinlian's actions. One day of love is because two people love each other and have deep feelings for each other, so they choose to be together. 2 days of love is because the two of them are very happy living together, supporting each other and forming a tacit understanding. 3 days of love was because the two of them could better explore each other's potential, learn from each other, and grow into better people. 4 days of love was because the two of them had the same interests and hobbies and could do what they liked together to spend a good time. 5 days of love was because the two of them had mutual understanding and tolerance, so they could better face all kinds of challenges and difficulties in life. The above are just some possible reasons. In fact, the reasons for Heavenly Love vary from person to person. Everyone has their own unique thoughts and feelings. You can judge whether to choose Heavenly Love according to your actual situation.
