This article be! Tragedy has no distinction between offense and defeat.
From a long time ago, the souls of time-travelers have reincarnated in this world. Their reincarnation will only retain the memories before the time-travel, so the memories before the time-travel give them their own personalities.
So there are no major factors. There is actually no difference between them in their past lives and this one. It amounts to amnesia at best.
People all know it, and they kindly give them names in this life based on their names before they traveled through time, so that their lovers in the past life can find them more conveniently.
Male protagonist 1, Xinghe, is a human being. He only sees aberrations in his heart. He believes that love makes people weak.
Male protagonist 2 Yeyue, an elemental elf, only wants to accompany him. He does not want his love to hinder the belief in the advancement of the galaxy.
Yeyue: I like the way he shines with faith, but why doesn't there seem to be any room for love in your heart?
Xinghe: I finally understand that love will not make people weak, but I'm sorry, I may have to follow the same path of my previous life.
Ps, when the time traveler comes to this world, he can become any creature, elemental elves, monsters, humans, or even... It's possible.
P. S. The end point of human evolution is elemental creatures, which is why there is no distinction between attacking and receiving.
P. S. I don't know if this book counts as be, because his ending is indeed be, but he can be happy, but the happy ending is not in this book, but in the protagonist of another book.
Intention: Love can never hinder people's progress
