If you force yourself not to think about some things, you will stop thinking about them. But there are some people who you force yourself not to think about no matter how hard they are, but they will always be there. We always have no way to go against our hearts. Not everything can follow our thoughts and bodies and leave together. Once some people or things live in your heart, no matter how you try to escape, it will be useless, because they have been deeply ingrained in your heart, and we cannot escape our fate.
