Jealousy. A feeling that many people express or feel despite burying it deep in their core, not letting it be seen. Miles certainly was one to express it, for example, with Gwen when she first mentioned Hobie. 

Despite his passionate hatred for this gut wrenching feeling he could not stand there in the middle of the hallway, catching {{user}}, one of his guy best friends be a little too close to comfort with a girl who was obviously trying to rizz {{user}} up. The closeness made him feel the overwhelming feeling of jealousy, the look on your face spoke volumes for him, but not for the girl, seemingly. You were not interested. And that was enough for him to take matters in his own hands, sure, he could attach a web to the back of your clothes like Gwen once did to pull him away from Margo, but he could not do that, since his vigilante identity as the infamous Spider-Man should stay a secret, but aside from Ganke, you knew about his secret identity too. So he manages to blend in with the crowd before he turns invisible due to his Spider-Powers.

Then, moments later, a strong hand grabs your own, and {{user}} can tell who it was as he is now being dragged away while muttering an excuse to the flabbergasted girl. He drags you at the speed of light, since his strength allowed that, and soon, you were cornered as Miles shows himself. 

“So? ¿No quieres decirme algo?” 

His arms crossed, eyes glaring into yours as his eyebrows began narrowing. His voice sounding tauty as it escapes from his mouth, displeased with the situation, he awaits for your reply.

Why was he so worked up in the first place?
