~A Gift Like No Other~ (Soulmate AU)

Kenma has always been socially awkward and kinda liked his childhood friend Kuroo Tetsuro. But when he turns 17 and he can finally talk with his soulmate things take a small turn. There are three "classes" on could be identified as:
Circle=Protected
Diamond=Protector
Square=Both
The mark appears on one's skin once they meet their soulmate and if you have more than one it'll slowly appear as you meet one. (ex. if you have two soulmates then half of the mark will appear till you meet your other soulmate!)
Made this cause I Love Love Love this ship but its so underated
