Inko Midoriya had always been good friends with Mitsuki Bakugou, they have been best friends throughout their middle and highschool years. They were inseparable, Mitsuki was always a stubborn girl, and Inko was always a caring and kind little girl, together they became the best duo, the best of friends.
Even through their college years and times where they had to go their own ways for their own good and future, they still had a strong stable friendship. They shared good news and bad news when meeting up with eachother, but no matter what, nothing will be better than their friendship.
Mitsuki always loved how Inko was so supportive and caring, cause when those traits were needed they always came in hand. Mitsuki was always sure to give back the kindness, especially when Inko had complications with her husband.
Mitsuki was always making sure Inko was in the best care, and taken care of. She had known Inko didn't have the best relationship with her family, nor the best childhood. That's why Inko and her were always such good friends, Inko could always trust Mitsuki.
The surprising part is that, they both ended up getting pregnant around the same time, that was before Inko and her husband had divorced of course. Mitsuki had her son first before Inko, only for Inko son to be born a month later.
They both had amazing names picked out, Inko was naming her son Izuku Midoriya, while Mitsuki and her husband Masaru named their son Katsuki Bakugou.
As years passed, Katsuki and Izuku's bond had grown. Always having sleepovers, playing outside everyday, going to each others houses, pretending to be hero's.
But things slowly changed as middle school came around.
Katsuki had more attitude, more confidence, more powerful, less grateful, didn't think before he did things.
Izuku was soon shutdown because he had lost his best friend, his only friend.
Though! Izuku was not going to give up now! No matter how many times Katsuki told Izuku how stupid he was, or dumb.
Even when Katsuki bullied him for being a quirkless loser, Izuku still followed right behind Katsuki, or so he calls "Kacchan".
Izuku just wanted to be his friend, he didn't care if Katsuki would call him names or call him "stupid Deku". He knew Katsuki well, Izuku knew Katsuki didn't want to be known as weak.
Izuku made a promise when he was younger, to always love and care kacchan, no matter how mean he can be, he will always follow kacchan.
