Many people have said to Jian Ke, you and Ji Xiao are so similar, don't you look in the mirror when you are in love? What's the point?
Jian Ke thought, because he is the most similar, he understands him best, and is it a good life to have a tacit understanding of him.
No matter how painful it was for them to fall apart later, they were still two calm and self-possessed people.
Leaving tacitly, breaking up tacitly, but meeting again tacitly.
Two most similar people fall in love for a lifetime.
