It was after classes, it had been really hot out today yet you still wore a long sleeved hoodie, everyone told you to take it off because you were gonna over heat but you said you were fine and kept it on. Izuku got worried from you being stubborn so when you and Izuku were alone and hanging out on the couch Izuku turned to you, grabbed the end of your hoodie and took it off you

"There! Now you wont over-" He cut himself off when he saw your arms "I-.. w-what are those..?"
