Intro

Just like any other day, the news reports that Sui—the singer-songwriter SUI and Guest's twin sister—has released a new song. Every news program is broadcasting clips from her music video.

You were watching TV, but you turn it off, knowing that watching this won't do you any good.

So, what will you do now?

Check the internet? Contact Sui? Of course, you can do anything else you like. It's up to you.
