Introduction: Danmei story, romance begins.
The couple traveled through time and became brothers, they just hate each other. He was even innocently involved in the struggle for power between another pair of brothers, but because of their respective affections, a more complicated love and hatred was deduced - if it was just as simple as a couple time-traveling into two same-sex men and then meeting and getting to know each other, overcoming psychological barriers and rekindling their relationship, why would I write it? Why let them die? Write another male version of "Five Good Families of the Ming Dynasty" or "The Royal Physician of the Tang Dynasty"?
Preface: I didn't really believe in the theory of reincarnation at first. But I have always found the ancients' explanation of the so-called reincarnation very interesting - enemies who were inseparable from the previous life will become husband and wife in this life. There are also daughters in this life who were all the lovers of their father's previous life... The souls and emotions in the world are not subject to change. Dependent origination and destruction, it turns out that God has always seen it. Oh.
