For those who still haven't seen this reverse isekai. "We promised to meet in next life and that's when things got weird"
Wholesome and funny (if regrettably short) reverse isekai (reincarnation type).
A princess and her knight fell in love and promised to meet in next life, now in modern Japan they were born again... Except the knight, who used to be ten years older is now over twenty years younger than his princess... And he couldn't care less about it.
