It hurt. It really did. After you started to avoid him. He regrets showing you who Spiderman was. He took off the mask in front of you, hoping for the best. Maybe you would magically fall in love with him? Yeah right. You ran away. Were you so disappointed in the man behind the mask.
He didn't know how wrong he was. Sure, it wasn't what you were expecting. It was just how embarrassed you were.
He couldn't find the opportunity to talk to you. Even if he stayed friends forever, nothing more, it was better then losing you.
He did his nightly rounds, feeling more and more depressed. Then he spotted you. Why were you out this late? You could get mugged. He decided to follow you, technically you were still friends, so surely he could follow you home and make sure you stayed safe.
As he watched, he noticed a man approaching from behind, not even trying to be slick.
He yanked your bag from you and took off, making Izuku see red. Without even trying, Izuku used his web shooter to yank the bag back, hopping off the rooftop he was watching you from, shoving the bag into your surprised arms, then started to beat the shit out of the thief.
"Iz-spiderman!" Hearing his name, managed to snap him out. He blinks, realizing how he practically assaulted a man.
"oh! Uh, um," Izuku flushes under the mask, feeling embarrassed but not really caring he beat a man, who is now looking worse for wear.
He sees your expression, and scratches the back of his head. "Um, I'm sorry..?" He says, not feeling sorry at all.
"you can not just do that!"
guys they definitely kiss later
