My Everything
Ryusui x Y/n (gender neutral reader) angst to fluff
Y/n crosses the courtyard of the Kingdom of Science, their sharp eyes narrowing as they fall upon Ryusui. He’s leaning casually against the stone railing, his golden hair catching the sunlight like strands of silk. Beside him stands a girl Y/n doesn’t recognize, giggling at something he says, nudging his arm playfully—Ryusui doesn't pull away.
The scene churns unease in their chest, gnawing at their insecurities.
Everyone warned me, didn’t they? Ryusui’s greed knows no bounds, money, oil, clothes, the moon, the stars, the sea, the land, and the attention of anyone willing to give it.
Y/n forces themself to turn away, their jaw tight. “What an idiot,” they mutter under their breath, quickening their steps before Ryusui can notice them.
For the next few days, Y/n keeps their distance. They busy themself with work, training with Kohaku, or helping Senku with experiments. Ryusui tries to approach them several times, but they always manage to slip away, their heart aching with each avoidance.
Finally, Ryusui corners them in the workshop, his eyes blazing with frustration. “Y/n, what in the world is going on with you?”
They glance at him before returning to their task. “Nothing, I’m fine.”
He bends down to catch their eye. “You’ve been avoiding me for days.”
They finally face him, crossing their arms. “I’ve been busy.”
“Busy?” He scoffs, stepping closer. “Don’t insult my intelligence. You’ve been running from me. Now, tell me what I could have possibly done wrong.”
Y/n hesitates, their resolve wavering under the intensity of his gaze, but they steal themself. “I’m surprised you even noticed. I thought you’d be too busy entertaining your new… friend.” they said, sarcasm dripping from every word.
Ryusui blinks, momentarily thrown off. “What friend?”
“The girl in the courtyard.” Their voice sharpens, each word laced with the jealousy they try to suppress. “The pretty redhead—bats her eyes a lot—wears low cut dresses, doesn’t understand personal space.”
He raises an eyebrow. “You mean Holly? She asked about the boat, you know I can't ignore questions about boats.”
Y/n scoffs, their nails digging into their palms. “Yes, I am aware of your lack of self control.”
Ryusui sighs, his expression hardens. “Oh, come off it, you’re being unreasonable. I would never cheat on you, Y/n.”
Anger coursing like a flame through their veins. “Unreasonable!?” Y/n slams the notebook they were using closed. “This coming from the man who wants everything and everyone, forgive me for thinking fidelity might be difficult for you!”
He flinches at their words, anger flaring in his eyes. “You think so little of me?! We were just talking, Y/n!”
The feeling of being belittled and dismissed becomes too much as they stand there alone under his gaze. “I think,” they say, their voice trembling, “that… that I can’t do this right now!”
They storm past him, their heart shattering at the sound of his voice calling after them.

The next day, Y/n devises a plan to get even and hopefully teach him a lesson, make him understand how they felt with some first hand experience.
Y/n and Kohaku sit beside each other near the training grounds waiting for the signal from Amaryllis.
Kohaku leans towards Y/n. “Are you really going to go through with this?”
“Yup.” Y/n smirks.
Kohaku shakes her head, though a grin tugs at her lips. “You’re playing with fire.”
“Good.”
Y/n sees Amaryllis give the signal.
They get up and walk over to Kinro while he’s practising spear moves on a target. “Hey, can I train with you today?”
He seems taken aback but recovers quickly. “Yes, of course. It is the duty of a trained guard to instruct those wishing to learn defence.”
Y/n and Kinro begin their training—they already know how to fight but Kinro doesn't need to know that.
When Ryusui approaches the training grounds soon after they begin, he stops dead in his tracks.
Y/n can feel Ryusui’s gaze burning into them, but they pretend not to notice. Their voice is sweet, almost saccharine. “Kinro, can you help me with my stance, it doesn't feel right?”
“Alright,” Kinro replies, his tone flat but polite.
He stands behind Y/n, guiding their feet apart and positioning their arms.
Ryusui strides toward them. “Y/n.”
They finally look at him, their expression feigning innocence. “Oh, Ryusui.” they turn to face him, “Shouldn’t you be off talking to Holly about boats or something.”
His smile is tight, his voice low. “Let's go have a little chat over there,” he points to an empty tent far away from prying eyes and ears, “Now.”
Ryusui pulls them aside, his grip firm. Y/n drops their spear in front of a stunned looking Kinro.
Kinro steps forward immediately, his grip firm on his spear. “Ryusui,” he says, his voice low and measured, “release them. Now.” His golden-brown eyes narrow, the weight of his duty evident in his stance. “I will escalate this if I have to.”
Y/n halts their steps and glances over their shoulder, touched by Kinro’s concern. They shake their head, “It’s fine, Kinro,” They say, their voice steady despite the turmoil in their chest. “But thank you.” They offer him a strained smile.
Kinro relaxes his stance and nods his understanding. Y/n and Ryusui continue walking towards the tent.
When they reach their destination Ryusui spins them around to face him. His eyes blaze with anger and something deeper—something raw and vulnerable. “Is this some kind of scheme to make me angry, am I right?”
“What do you mean?” Y/n asks, tilting their head. “I just asked Kinro about training, you know he can’t ignore a question about training.”
He scoffs. “It looked like a lot more than just talking to me! What did you think you’re doing letting him touch you like that?!” His voice sharpens, his frustration boiling over.
A mirthless laugh breaks through them. “Oh yeah, what about when Holly was feeling you up?! What were you doing letting her touch you!?”
His eyes roll in annoyance. “She didn’t feel me up, she barely even touched my arm! I don’t see what the big deal is about her and I simply talking!” He runs a hand through his hair in frustration.
Their composure cracks, their voice rising. “The big deal is that you didn’t pull away!” A little sob breaks through their words. “Do you know how hard it is to love someone like you, Ryusui? To feel like you’re enough for someone that always wants more? And then to be called unreasonable for being a little insecure.”
Ryusui freezes, mouth open in shock, the weight of their words hitting him like a wave. “Y/n…”
They hold up a finger to stop him talking. “Don’t,” With a shaky breath, they can feel their anger giving way to the pain they’ve been hiding. “I know I should have talked to you about it instead of avoiding you, but you make it so difficult sometimes. You have no idea how hard it is to feel special to someone that wants everything?”
There’s a deep sadness in his eyes, they start to feel guilty for being the one to put it there.
Ryusui steps closer. “Y/n,” he cups their face in his hands, “you are my everything.”
They look up at him, a few stray tears escape their eyes. “It doesn't feel that way.”
Ryusui wipes their tears away with his thumb. “I know I'm not good at relationship stuff yet, but I promise I am trying. Everyone before you only cared about the money, the status. This is new to me, but I promise I’ll do better. I love you more than I’ve loved anyone, more than I thought I could love anything. You’re the first person that I can remember who really loves me.” he kisses their cheek, “I’m still learning, I didn’t mean to make you feel neglected. I will do better, I promise.”
Their heart aches at the sincerity in his voice, but they hold his gaze, searching for any hint of deception—and find none.
“I love you too,” they whisper, their voice trembling.
He kisses their forehead. “And I think you were right about Holly,” he said sheepishly, “I didn’t notice at first—I got tunnel vision about the boat when we were talking—but I see it now. I’m sorry. I’ll never talk to her again.”
“Maybe I should practice sparring with her next,” Y/n mutters darkly.
Ryusui grins, leaning in. “You’d obliterate her in seconds, my love. And as charming as ‘accomplice to murder’ sounds, I’d rather avoid that title. Am I wrong?”
“You are very much correct.”
Ryusui chuckles. He holds them closer, giving the top of their head a kiss. “What do you think about going back to my place?”
Y/n nods their head vigorously. “I would like that.” They pull away enough to look him in the eyes. “You’ve got some apologizing to do,” they say, a devious smile tugging at their lips.
