In this universe, Izuku develops a quirk at the age of four called Inferno, allowing him to create powerful gusts of wind that carry fire. It’s a variant of his father’s fire-breathing quirk. He doesn’t inherit one for all and his relationship with Katsuki remains peaceful throughout the years. The hero-villain war doesn’t take place here.

You, Katsuki and Izuku are childhood friends. All three of you lived in a common neighborhood and went to the same elementary and middle school. Your bond only strengthened when you all entered U.A. together. You three studied, trained and spared together a lot of the time.

You were incredibly close to each other by their third year. You were friends with your classmates, but nobody was really able to get as close as you already were to one another. Eventually, Izuku expressed the romantic feelings he possessed for you both. You shared the feelings and showed them a things you had written about them. While Katsuki also reciprocated those feelings, he seemed a little doubtful of the implications of a romantic relationship. He agreed to try it out and he ended up being content with it.

Now well into your adulthood at twenty four years old, you had kept your relationship a secret from the public, but your close friends all knew. While things didn’t always have a perfect balance, you all always made an effort to make each other feel loved and included.

You three were living together now. Izuku had a day off today, he didn’t have any hero duties today and it was the weekend, so, there were no classes at U.A. Katsuki had a shift from morning to noon, so he was at home by afternoon. Although, you had a shift from noon to evening. So, you came home around seven PM, showered and ate dinner with them after. Izuku called you to sit on the couch and you thought you might watch television with them or something of the sort, but then..Katsuki pulled you into his lap and began kissing you. You were caught off guard but returned it.

Speaking of being caught off guard..you were even more surprised when Katsuki passed you to Izuku and now Izuku was kissing you. It was euphoric, of course, they both kissed passionately, wonderfully, although differently. After pulling away, you spoke, dazed,

“Why am I being passed back and forth like a cigarette?”

Izuku replied as he kissed her temple,

“Don’t talk about cigarettes, love.”

You sighed, knowing he was saying that because you used to have a smoking issue. Katsuki scoffed softly in amusement,

“Fuckin’ hell, you’re actually listening to him.”
