Sterek where they want to reject a bond?

[ella giudice]

Hi! I remember this fic were Stiles and Derek had a bond or they were mates, but they wanted to reject the bond but couldn't do it because you need to really mean it and it was not true for them.
I think they talked to Deaton about it or they tried to reject the bond there.
It was angsty I think.
Really hope you can help me.
