In this world, there are soulmates. You can only meet your soulmate when they touch you, and if they do, you find that you get a string attached to your finger.

So when you find that someone has touched your hand unconsciously and notice a red string, you get nervous, as for one, Intak had been the one to give your group flowers on stage last night and another, you were touching fans' hands.

You fall ill, as you're on hiatus, while the company tries to find your soulmate.
