Derek likes to pick on Stiles, push him against the wall, or grab his neck or bang his head against the steering wheel (but that was only one time) This time Derek shoved Stiles to the wall and gets a unexpected response.
Stiles walked into his room throwing his bookbag and jacket into the floor next to his desk. As soon as he closed the door something grabbed his shirt and he was shoved against the wall. He yelped and looked up to see glowering Derek.
Derek was expecting Stiles to get angry and snap at him, but instead Stiles body starts shaking and Derek smelled tears. Stiles was crying getting closer to a full blown sob. Derek was stunned and he let Stiles go, Stiles slid down the wall and hugged his knees still crying.
"Why me, what did I do to deserve this, Scott is ignoring me all wrapped up in Allison, Jackson never ceased to make my life a living hell and you for always slamming me into something." Stiles whimper and slowly rocked back and forth.
Derek was floored, he wasn't expected Stiles to break down crying like that, he doesn't know how to deal with that, he was thinking about leaving and just let Stiles be, but something was telling him not to leave.
Stiles sobs quieted down to sniffles, Derek groaned and picked Stiles up and placed him on the bed and then he sat next to him.
"Sorry for pushing you agaist the wall," he muttered. "And I will talk to the boys about treating you better." Derek said gruffly.
Stiles nodded and curled against him rubbing his tears on Derek's shirt.
Derek hesitantly rest his hand on Stiles' head rubbed his short hair. Stiles let out a soft purr like noise and slowly went to sleep.
