You Were Born, but I Was Not yet Born - I Was Born, but You Are Already Old

This is an extremely beautified product. ＣCP is Ji He. In fact, He Shen in real history is not ugly, but rather wretched as described by Ji Xiaolan (it may also be because of his age). Moreover, Ji Xiaolan is 26 years older than He Shen. Since this is a novel, we can pursue the same state of being at forty as at twenty. So, let's say! The two people's looks are relatively good, well, not bad, at least not ugly. Ji Xiaolan-He Shen (after time travel). Standard black-bellied attacks and tsundere attacks.
