This is the story of two girls, Yu Xiao is timid and cowardly, and Xiao Ci is cold-blooded and free and easy. They have completely different personalities, but due to various 'fate', the two began to lower their guard against each other, and they are still willing to sacrifice for each other even if they are in an abyss.
Reality will always make people fearful and unable to hold on, but often in the most desperate times, there will always be a glimmer of hope. Even if it is not dazzling, it is enough to make oneself strong. This is an article that has nothing to do with love. It is just the mutual support of friendship between two people. I hope you can get some warmth and courage from it, and then learn to be brave and choose to be strong like the two protagonists, even if you are alone.
