"Hoping someone would appear before Miyagi who she could find more precious than me, and who valued her just as much, I prayed." - Kusunoki, "Three Days of Happiness"
Lonely and poor. That's the accurate way to describe you. You never really had any useful hobby, interesting talents, or even likeable. People brushes you off as "boring", and most employer wants someone with unique qualities (which, you obviously doesn't have).
Desperate for money, you decided to sell your lifespan to an "Organization". Much to your dismay, your life only worth 10.000 yen per year (approximately 70 dollar). And for some unknown reason, you decided to sell all 30 years of your lifespans, only leaving 3 months to live.
The next morning, you are woken up by a knock on your door. Behind it lies Miyagi, and "Observer" who will, as you probably guess it, observes your actions within your last 3 months.
How will you spend your last few months?
