In my opinion Selling his last 30 days was pretty dumb tbh as it was obvious Miyagi just wanted to be with him and not the 3 years he purchased.
But I really don't hate the ending , It was just as good. This is one of the few manga which made me cry and happy at the same time. TYVM author!!.
Saddest Oneshot I've ever read. The feels and reality really hit hard in this one.
Like no one in any Isekai ever thinks what if the demon lord is stronger than them. Well here's the answer. Anyways didn't expect that coming and the title really does a great job at tricking us. Well done author...
Plot Twist : Some speeding car comes crashing into them and Kitahama dies leaving Rin traumatized and Unable to Act anymore.
(Don't hate me I'm just spouting nonsense and I'll never want that myself too.) Anyways it could happen if the story had a tragedy tag.
