Saiki Kusuo was a strange boy.
Even ignoring the fact that he had supernatural powers, there was one other thing about him that was strange.
The word on his wrist.
In this world, everyone has the first thing their soulmate will say to them written on their wrist. Usually soulmates have them on opposite wrists - it's sort of silly, but Saiki has always believed that it's so that, when walking side by side, they'll hold hands with the hands of the wrists that their words are on.
Anyway, because of this phenomenon, whenever you meet someone for the very first time, you can't just say something like 'Hi' or 'Nice to meet you'. No, you have to pick out a special phrase when you're at a certain age - or, in some places, a phrase will be assigned to you at birth - and you have to say that strange, random phrase, before you can continue on and have a normal conversation with the person. Even when you bump into someone on the street, you're supposed to say your phrase before apologizing.
People have phrases like 'The monkey ate the handbasket!' or 'Socks with turkeys are my favorite!' - things that you would, hopefully, never say in normal conversation.
Which is why Saiki's phrase, the one on his wrist, was so odd.
'Sorry'.
Obviously he would meet someone through some accident - he'd bump into them on the street, or they would be a waiter who would spill his order. Something like that. But as previously stated, even then you're supposed to say your phrase before apologizing.
But Saiki already knew why his soulmate would say that instead of their phrase.
Saiki spoke through telepathy.
Because of this, he never actually did 'speak' to anyone. And apparently that trend would continue when he met his soulmate. Therefore, nothing was on his soulmate's wrist. And to be honest, if that had happened to Saiki, he'd probably think he had no soulmate. Which meant that was what his soulmate thought.
Which was why his soulmate wouldn't bother saying their special phrase - if they had one at all.
Oh well. He'd explain it to them once he'd met them.
