In this world, most of the interactions between people are actually superficial. But once you go deeper, you'll realize that the hearts of people are like a maze. Some will stop at the door, while others will accompany you inside. When you think you've lost your way, you find that the other person has already been waiting for you ahead, so all that complexity and unease eventually turn into a shared playground. Of course, there are also some people who are only suitable for walking together on the bright, open road. It's not insincerity; it's just that going deeper makes both parties tired. So, some people are suitable for navigating the maze together, and some are suitable for traveling part of the journey. Both types of relationships are genuine.
