I really would like to thank Hato for thinking the scenario and Ichiju for illustrate this story. It's one of the most beautiful Sakuya x Rinnosuke story I have read to date.
I really liked those last lines she said. Very beautiful.
That's whyI chose to be a human with one life.I may lose this feeling that I have for you.Besides, if living forever means to have your feelings completely worn-out, I would rather keep my limited life.Otherwise,It is quite easy to forget that there will be anxiety between youkai and human during a danmaku... I see, interesting answer.
