Rebirth Doesn't Take Me with You, Right?

Huan Ning has always believed that one of the great regrets in life is that people cannot have youth and the understanding of youth at the same time. What would you do if you could go back to being a teenager? Hug your parents who don't have too many gray hairs, and meet the girl who always makes you blush. It's the most perfect white moonlight in the best time. Go to the dismantled park to play on the slide again, look at the old yellow dog, and change the answer to the multiple-choice question... There are also those who have seen the last side of their lives inadvertently. After rebirth, they must draw a rounder full stop, right? And… Wait! Isn't it me who is reborn? ? Is it her? ! ? ? ? Rebirth doesn't take me with you, right? !
