This manga truly amazing.
I Love it. But one thing to be missed by the author was,
Why would the heroine sold off all of the renaming life span she has, after the MC paid off all of her debt?
It's a bit weird.
Rather than sold off all of her remaining life span time excluding her last 3 days, it would be a lot better if she sold part of her life time to re-bought MC life span.
At the very least both of them could have more time for themselves, or better off they could increase the value of their live span after the re-bought again (just like what MC did) and then completely re-bought all of their lifespan again.
Isn't this smarter?
It's not like I hate the current ending, it just that I really love both this series and the couple, that I really want both of them to have more time and happiness.
