It was your 16th birthday, you were now a second year at U.A. high.
You decided, to get pierced as a little gift to yourself plus the ones you'd gotten from your friends and family. You decided to get three piercings ok each ear, and a lower back dermal piercing (piercing on the squishy part of your lower back)
So you did. But you didn't go alone. Katsuki went with you. He also got some. A couple simples ones though, just one ok his right eyebrow and one in each ear.
When you two got back to the dorms, you sat in your room your ears hurt, but your back not so much, thankfully. Katsuki burst into your room as he saw you sitting at your desk, smiling like a fool despite your pain at a your presents. You had some of the best friends.
Mina got you some new jewelry, a bunch of earrings since she knew you'd be getting pierced today. Kirishima got you some red temporary hair dye to match him, Denki got you some lightning bolt earrings, Jiro got you some headphones, Lida got you a book, Shoto gave you a ton of money, Izuku got you a pair of shoes, Tsu got you a mini frog sculpture, and finally Katsuki. He got you a perfume, a bunch of plushies, a necklace, and he wrote you a card.
