Awww its so isss, i bet stiles is the stubborn one tho cuz Derek is an ass ok. He jumps into danger and protects the pack and smiles adorably and has the softest hair. While Derek realizing that he CARES for stiles might actually be quite sweet and pure.
Do you ever think about Sterek couple fights? CAUSE I DO! Like they'd be so absurd! Stiles' jeep would break down in the middle of the road and Derek would go on and on about how he hates that thing all the while fixing it and they are just arguing until Stiles dozes off cuz it's really late and they've been out for hours and Derek shrugs off his jacket and covers Stiles sleeping body all the while bitching about the jeep but keeping it low cuz shhh Stiles is sleeping and he goes back to 1/2
