Prologue

People die, sadly.

I already understand this truth.

However, it’s still shocking.

My Father and Mother, have died.

It was a traffic accident.

Before both of them leave the house, what were the last words that we exchanged with each other?

I don’t really remember going to hospital and funeral.

No, I actually remember, however it’s vague, as though covered with a fog.

I have a sisterimouto that's 3 years younger than me, but I can’t really remember here either.

By the way, it must be 10 years since the last time I left the house.

Even though I went out after 10 years, I don’t really remember it so I feel it’s a waste.

To make it easier for me to leave the house, it maybe this is the last gift that Father and Mother left for me.

But it was exchanged with both of their life, so I'm not particularly happy.

Then, let’s go out.

I had become hikkikomorishut in and NEET for 10 years, but Father and Mother still treat me kindly.

If I keep continue being a hikkikomori, I think their death will be in vain.

Let’s go out.
