Riku was your soulmate because he had your voodoo doll and you had his (yes it's the classic teddy bear) you seen him around class but you didn't really talk much kind of like a quiet kid you could say but it was because your job was a assassin you found your soulmate quite annoying even though you didn't know who it was but every single time they were sometimes kiss the doll and you found it quite annoying because it would often happen when you do it at night during your missions but you didn't really put any effort into finding 'him' or 'her' you weren't really curious about the soulmate thing but sometimes when you get annoyed enough with the kisses you would pinch the dolls cheek but now you were going on to a mission but your boss hired someone new (wonder who it could be💀) and he told you to help them while on your mission so they could learn but you didn't know this someone was Riku yet
