Katsuki was happy, it had been a week since he had talked to Izuku. It was great! Izuku started calling him 'Kacchan' again, that was the one the third day of them talking again.
Katsuki was preparing for Izuku's birthday, which was only in three days. Finding the safe was easy enough, getting the code for it was not. Mitsuki prided herself on keeping Inko's secrets.
But Katsuki knew she'd cave when she learned that this was for Izuku, she loved Izuku like he was her son. Not that Katsuki would mind if his Ma straight up adopted Izuku. That was an idea actually, "hey Ma!" Katsuki had yelled downstairs to get her attention, "I might have an idea for a gift for Izuku!"
"What is it brat?" Mitsuki asked, she and Katsuki's relationship has always been like this, Mitsuki was more of a tough love type of mother. Not that Katsuki didn't mind or anything.
"I was think that maybe you could adopt Izuku," he said coming down the stairs with the safe in his arms, "it is Izuku's birthday in three days."
"Hmmm, maybe. I'll see what your father thinks," Mitsuki said as she left to go get her husband, Masaru was the exact opposite of his wife, quiet and shy. Coming back into the room Mitsuki looked pleased with herself, "Masaru said that he'll get the papers from your homeroom teacher."
"Perfect, also what's the code to this damn safe! Izuku's going to need it for when he opens it up," Katsuki said as he gently put the safe on the table, "it's full of uncle Hasasi's stuff."
"Right, I'll get that ready for him, maybe we'll but the adoption papers inside of it," Mitsuki said as she quickly opened the safe and wrote the code down on a piece of paper, "here's the code. Maybe put in a card wishing him a happy birthday."

Three days have passed and it was now Izuku's birthday. Katsuki had quickly slide the card under Izuku's dorm door before leaving. He was going to make Izuku his favorite breakfast for his birthday. Thank god it was a Saturday.
Katsuki made quick work on Izuku's breakfast, which was a simple chocolate chip pancakes. He made it the same way Inko did. Walking upstairs to Izuku's room Katsuki slowly opened the door and quietly walking inside.
"Izuku, wake up," Katsuki said quietly as he gently shook Izuku's shoulder, "happy birthday."
Izuku shot up at that before looking at Katsuki and yawning, "good morning Kacchan, is that breakfast for me?" Izuku ask while stretching his tired muscles, "wait is it chocolate chip pancakes?"
"Yep, made them just like how Auntie Inko did," Katsuki said while handing Izuku the plate, "your birthday card is by the door, I'll quickly head to my room to get your gift."
Katsuki got up to leave, before he could Izuku stopped him, "thanks Kacchan, this is going to be the best birthday day ever!"
"Yeah it will, little bro," Katsuki said before walking out leaving Izuku confused at the statement, smiling softly Katsuki made it to his dorm and got the safe.
~{ÙwÚ}~
Izuku sat on the floor of his dorm when Katsuki got back with a giant box in his hands, "what's that Kacchan?" Izuku asked looking up at Kastuki.
"It's your gift nerd," Katsuki said while sitting down siding the box over to Izuku, "the card actually has the code for your gift."
"Oh is it the safe?" Izuku asked while opening the gift to find the safe, "it looks just like I remember it." Opening the safe with the code Izuku started crying at what he read, inside the safe was adoption papers that were already signed by Mitsuki and Masaru. "That's why you called me little bro!"
"Yep, it was actually my idea to have you as my brother," Katsuki said as hugged Izuku close to him, "it was actually in Auntie's will that we become siblings."
"I love you big brother," Izuku said hugging Katsuki back while smiling happily for the first time in what felt like years.
"I love you too, little bro," Kastuki said as he closed his eyes and thanked whatever god out there that this had worked out in the end.
