Hello! Welcome to my story! First of all I must tell you what a soulmate is.

There are 2 people linked together with a red string which and be broken by true love. But if your soulmate dies you will also die. Before you have found your soulmate you have a red string that fades off. If you are within 2-3 miles of your soulmate the string will materialize and pull you towards your soulmate. Once you are tied to your soulmate, you have to share a kiss with so much love and admiration that it breaks.

The string doesn't care about gender. If you don't love your soulmate the string will break and you both will die. Most soulmates are friends due to this fact.

Now that you know this, lets head to the household of Shōta Aizawa.
