Open Relationship (KiriBakuTodoDeku)

Prologue (Bakugou)

This is starting when Izuku and Bakugou are 10.

"Izuku, honey, can you get the door?" Inko says from somewhere within their apartment. I feel bad, coming to them after how I've treated Deku, but I don't know who else I could turn to. I know my dad won't be supportive of what I'm about to ask, and I just don't feel comfortable talking to the Old Hag.

The door opens to reveal my old friend. The moment he sees me, he starts cowering. Maybe coming here was a mistake. "K-k-kacchan, what are you doing here?" he stutters out.

"I'm not here to hurt you, Nerd," I respond sheepishly. I'm a little embarrassed by what I want to ask of him. What will he think of me? A girl asking to try on his clothes. "I wanted to see if you could help me with something."

Deku waves me in, and I follow him through to the living room, taking my shoes off before coming further than the entryway. It's now or never. How do I even word what I want to ask him?

"W-what did you need help with, K-kacchan?"

"Can I try on your clothes?" I practically whisper. The nerd probably couldn't even hear what I asked.

"W-what was that?"

I groan. Speaking up a little, I ask again, "C-could I try on your clothes, Deku?"

He gives me a questioning look, but before he can answer, Inko comes into the room to ask him who was at the door. She stops when she sees me. "Katsuki, what are you doing here?"

I'm about to lose my nerve and just run. This is too embarrassing. Asking the damn nerd was one thing, but explaining this to my mom's best friend? I don't think I have the strength to do that.

"Sh-she was asking t-to try on my cl-clothes," Deku responds for me as if he could read my expression.

Inko gives me a small, sympathetic smile. "Go ahead you two, but Izuku, give her some privacy while she changes. Or should I say him, Katsuki?"

Somehow, her question lessens some of the tightness I've been feeling in my skin. It's as if her asking if I should be called him opened up the first crack of the outer layer that needs to be shed. Is that what's been wrong with me? I've always hated the girl clothes that I've been forced to wear my whole life, not really understanding why it bothered me. I came here because I was curious what it would feel like to wear boy's clothes in hopes that it would relieve the tight itchy feeling that's plagued me for a while. Am I really a boy born in a girl's body?

My face is flushed as I attempt to look anywhere except at Inko. Her words caught me off guard, and I need a chance to think on them.

"Come on, Kacchan." Deku seems to have gotten a little more confident seeing me flustered. Maybe he's realizing that I'm not quite as scary as I lead him to believe. "My clothes might be a little small, though, since I'm not as tall as you."

I shrug. I had already thought of that, but he always wears clothes that are a size or two too big for him anyways.

Once Deku has found some stuff that he thinks will fit me best, he slips out of his room to let me change. Just taking off this stupid dress is enough to make me feel better. Could Inko have figured out what's been wrong with me with just one request? I've been trying to figure this out for two years now. I thought it was just the clothes, but is it deeper than that? I've always hated my voice, it's just too high pitched, so I trained it over and over until it was deeper than the nerd's. I hate being forced into frilly dresses, but even the pants and shirts bother me too. Anything that can be construed as girl clothing. And my hair, oh how I hate this long hair. I've been too nervous to ask if I could cut it short. What if they tell me girls can't have short hair?
