The string was always on your finger for as long as you can remember, everyone is destined to find their soulmate one day. You being no exceptions as one day while you were completely surrounded by hilichurls, as they were getting close to you a man with red hair jumps in with a claymore and starts slashing at the hilichurls. You felt the string moving as you noticed that your string is connected to the man.

He stands there after defeating the last hilichurl, then turns his head to you.
