Perhaps one would call it a parasitic craving. Midoriya simply wished for something sweet to feast upon, but his boyfriend constantly reminded him that too much would cause a stomachache. Well, Midoriya didn't particularly mind the prospect of feeling ill after indulging in his saccharine, sublime sea of sardonic sugar.

When had such an anomalous craving latched onto Midoriya? Truth be told, he wasn't entirely certain—all that mattered to him was that sweet, sweet taste of sugar savaging his tongue, and that lip-smacking sensation of a rush of sugar crawling through his veins.

"Kacchan, I want just one more today. Anything will do."

Bakugou exhaled slowly and buried his face into Midoriya's chest. "No," Bakugou whispered in a stern growl as Midoriya tenderly caressed from the crowns of Bakugou's ears to his earlobes. "Deku, don't be a damn idiot. Ya promised to start cuttin' down on it slowly, yeah?" He sighed as Midoriya's chin rested over his shoulder.

"I know… Kacchan, I'm not trying to say I'm looking down on your opinion. I just can't help it." Bakugou rolled himself back onto Midoriya's lap so that his eyes met Midoriya's. "There are so many good choices. It's irresistible…" Midoriya lowered his head down to fully encompass his boyfriend's lips with his.

Love was sweet, but sugar was sweeter.

While Bakugou leisurely embraced the kiss bestowed upon him, Midoriya curled his arms around his boyfriend to augment their bitter tenacity. "Tch," muttered the ash-blonde. "Think you can make it until tomorrow? I'll make ya katsudon for breakfast." His thumb gently smudged across Midoriya's cheek.

With a dejected sigh, Midoriya replied, "Maybe…" He nuzzled his forehead into Bakugou's soft spikes of hair. "You're sweeter than any of it," he chuckled.

"Oh, fuck you," Bakugou groaned with the undertone of a snicker. "You stupid Deku—never knowing what's good for you. I know what's best for ya. Ain't that right?" A smirk nudged through his expression.

"Right," Midoriya giggled with notes of mirth humming from his being.

Later that night, Midoriya was unable to sleep. He was hungry. Desperate. Ravenous. He wanted just a sliver of sugar to sate the vibrant desire scratching at his tantalized mind.

I'm sorry, Kacchan, but nothing is as sweet as this, Midoriya thought while drinking up the zeal and the sweetness of his silver, sharp candy. All different kinds of forms, and all so sweet. Liquid, solid, gas, bottles, wrappers, packages… My favorite is this one. It hurts, but I don't mind. You always try to talk me out of it and prevent me from getting more, but you're taking away what makes me feel so good, happy, comforted… These tantalizing sweets that kill me the more I indulge in them are a part of my life now. Let me have this.

Honey spilled out in dazzling streams. It was thick and sweet. Dripping, winding, and pooling, a fountain of honey with a copper emanation splashed across Midoriya's body. He wanted to dance in the honey drooling from his limbs.

"You always think it's sad that I do these things, Kacchan," Midoriya whispered as the aggregation of honey thickened along his body. "You always tell me I shouldn't do this to myself. You always want to take me away from the things that make me happy. Your bitter is my sweet. You can never have too much of a good thing… It's so good. I'm numb from the adrenaline. I'm high from the pain. I'm intoxicated by how good it all feels. I wanna fill myself up completely…"

A bath of honey enveloped Midoriya's body.

"DEKU, USE YOUR FUCKING HEAD!"

The honey was so sickeningly sweet.

"Goddammit, please don't fucking do this to yourself anymore!"

Midoriya couldn't help but crave the sweetness of the honey—one of many forms he'd use to feed his sweet tooth.

"Deku, your fucking life is more important than any of this shit!"

The honey was too thick.

"Did the trips to the hospital teach you nothing?! Are all these scars, hangovers, and everything else worth it?!"

There was too much honey.

"Don't you understand how fucking much I care about you? That's why I don't want you to do this…"

The honey was too sweet.

I guess I cared more about myself than I cared about you, Kacchan. I'm sorry… I'm really sorry. I burdened you with everything, and you still stayed with me. But this honey…is just too addicting. I think I'm finally drowning in the sweetness I love so much. I know it isn't true, but I'll tell myself the same lie again: next time, for sure…I'll live sugar-free.

Midoriya expelled a chuckle as his silver, lethal "candy" slipped from between his fingers.

"Hey, Kacchan? How come the most painful things taste so sweet?"
