You've known Hara since as long as you remember. And you've been dying since as long as you remember.

Not that you remember a lot.

You were 16 years old when the accident happened— the one that left you orphaned. 16 years old when you were diagnosed with dementia. And since then, your best— and only friend, Hara, has been staying with you and taking care of you.

At 23 now, you didn't have a lot of time left with him.
