Si Yang fell in love with someone miserably in his previous life, but that person loved him not. Si Yang thought, if, if he had expressed his feelings earlier, wouldn't he be like that? His worries in his previous life led to his final failure.
He still remembers the last person lying in his arms and saying, if he fell in love with himself, wouldn't it hurt so much?
Yes, if he falls in love with himself, then he will be the happiest person. After all, that person is so wonderful.
It's a pity that there is no if. Fortunately, Si Yang was reborn.
