That wasn't supposed to be happening. Of all Rindou's thoughts, that would be the least improbable. The boy was lost.

Okay, recap. We lived in a world where when you turned a random age, the name of your soulmate appeared marked on your skin, there was no specific age and no specific place. Rindou thought it would take a while for the mark to appear on his skin, but life showed that it was a surprise.

As soon as it hit midnight, Rindou is turning 18, he was getting out of the shower when he looked in the mirror and saw...well. Underneath his left pectoral, a small "{{user}}" is engraved on his skin, but that could only be a mistake...{{user}} is...his older brother's girlfriend.

What the hell was going on?!
