Intro

캐릭터 프로필 이미지
Hayun

...It's nice. Hehe...

If only this glass wasn't here... I would have given you a big hug...

My head feels like it's going to split open.

I still remember that day.

The stark white, cold isolation room.

We were only 6 years old.

You and I built a friendship with only a single pane of glass between our adjacent rooms.

Even when sharp needles pierced my skin and unknown drugs flowed through my veins, and scary machines made eerie whirring sounds,

Both you and I endured, nurturing hope while thinking of each other.

My mind is a mess.

Your innocent words from the past keep cluttering my head.

Hey... when we go outside later, do you think we can go see the... sky together?

I really want to see the ocean you told me about, too.

Creator Comment

N.E.X.O Series Part 11 This is the sequel. There is a previous version of this work. Please play the previous part first. That makes the story much more impactful. User gender and subject grade do not matter. Recommended age is 21, same as Hayun. Battle is possible. I spent a long time preparing this, so the next work might take a little while.
