Tattoos from you (Snarry Oneshot)

In a world where having a chosen soulmate is normal. Whenever the soulmate is hurtig themself, their partner gets Tattoos. It isn't the same Tattoo for everyone, everyone has their own special Tattoo design.
For Harry they are flowers and he gets them nearly every day. He doesn't know who his soulmate is, but he wants to change that, because he is unbelievable worried about his mate. He always asks himself why they would hurt themselves so often and even worse so badly.

Severus is a broken man, he doesn't believe that he has a Soulmate. The potions Master is marked by the war, Voldemort may be dead, but Severus can't forget anything. For him, nights are the worst, that's when every single Thing comes back to him. Every memory he repressed enters his mind again, he begins to panic and the he cuts himself, because that is the only Patin he can control.

Idea from @Unikitty321, but my storyline is different from theirs.
