“Soda can tab without the ring in the middle means you have to give the other person a hug.

Soda can tab with a ring in them means that when given, you have to kiss the other person.

Soda can tab without a ring but having a circle in the middle means you have to do it with them.

But that’s only if you’re really comfortable with them”

Your friend, Scaramouche spoke dismissively as he shrugged before taking a sip of his soda can…

Huh, interesting… So that’s why your friends have been collecting soda tabs recently…

You two were currently watching one of your friends' basketball match, even if you didn’t understand how the game works, you still wanted to support them.

You decided to take the tab off of your soda can and ended up getting the one that meant “hug”

Scaramouche did the same and got the tab that meant you had to do it with him

But it wasn’t by accident, he knew how to get the 3 specific soda can tabs, but you didn’t know that.
