Chuuya has always liked Valentine's Day, even before he started dating people exclusively. Giving flowers and chocolates to people he loves, celebrating all forms of love, giving and receiving it—he loves it all.

Chuuya and Dazai were yet to properly celebrate Valentine's Day together, regrettably. Chuuya knows that if it were previous years, neither of them would probably have taken it seriously. Dazai likely would've gotten Chuuya a joke gift that made fun of him, and Chuuya likely would've gotten Dazai a gift that was equally not serious and likely would've involved hurting Dazai in some fashion.

Chuuya's glad they've both grown up a lot. He's glad they're on much better terms than they used to be.

Chuuya likes to go all out for Valentine's Day. While he could most certainly afford to buy the fanciest, most expensive chocolate for his loved ones, making the treats, in his opinion, is so much more personal and does a much better job at conveying his love. He made his own chocolate candies for all of his loved ones in the mafia—

But of course, Dazai gets something extra special. After all, the kind of love Chuuya feels for him is quite different from the love Chuuya feels for everyone else. So of course he had to make Dazai his own special treat.

Finally, the chocolate has cooled and hardened, and the homemade love-filled Valentine's candy is done. Chuuya washes the excess chocolate off of his hands, then he pulls out his ponytail, letting his hair down and flow, cascading over his shoulder. He picks up a piece of chocolate and puts it in his mouth, nearly melting at its deliciousness. Oh yes, Dazai will love these.

Chuuya places some of the chocolates on a plate, making sure to save most of them for later so Dazai can enjoy them over a long stretch of time. "Osamu?" Chuuya calls out. "Where are you?"

Chuuya goes up the stairs, where he could usually find Dazai laying on their bed. But alas, he is not there.

"Osamu?" Chuuya calls out again, now quieter, very perplexed as to why Dazai is nowhere to be found.

Suddenly, the front door opens, and Chuuya starts to panic. Was he really careless enough to leave it unlocked?

Chuuya sprints down the stairs, holding the tray firmly—only to see Dazai removing his shoes at the door, holding a fancy box in his hand.

Dazai looks up from the floor and sees Chuuya standing before him, one hand in his tray of candy, the other over his heart, his whole body glowing red. "Chuuya? Are you okay?"

"How did you sneak out without me noticing?!" Chuuya exclaims without even properly hearing Dazai's question, the red glow fading. "I thought someone broke in! I was ready to kick some ass!"

Normally, Dazai would chuckle at a comment like that, but he's too distracted by Chuuya's demeanor. "Well…I purposefully snuck out. I didn't want Chuuya to know that I was going out to get him his gift."

Chuuya can't help but turn a soft pink and that. "Really? You got me something?"

Dazai smiles and nods, holding the fancy box out in front of him, like a schoolgirl confessing to her crush. "Of course I did! How could I not get my sweet Chuuya a gift?"

Chuuya takes the box from Dazai's hands. It's very fancy and ornate. "My goodness, this is so pretty."

"I got you a special custom brownie from the nearby bakery. I hope you like it."

Chuuya puts a hand to his heart, feeling it flutter as a smile forms on his lips. "Oh, Osamu…you're so sweet. I love—"

Chuuya cuts himself off when he opens the box and sees the inside.

Inside of it is indeed a large brownie. It has been coated in melted chocolate and sprinkles, and looks delicious. However, on the front of it are edible letters that read, "I LOVE THAT DICK ♡".

Chuuya's eyebrows furrow. He thought Dazai was past the days of gag gifts like this.

He looks up at Dazai, giving him a look like that an estranged teenager gives to their parents when they intrude on them. "What the hell is this?"

Dazai puts on an innocent expression and puts a finger to his cheek. "A brownie, like I said! Doesn't it look delicious?"

Chuuya is very clearly unamused. "Why did you think this was an appropriate gift?"

"But I love it, Chuuya! And you!"

Chuuya looks away, irritated. "I thought you were past these shenanigans," he huffs.

"I didn't…anticipate this reaction. You really don't like it?"

Chuuya looks up at Dazai at that. He most certainly didn't expect a response like that. Dazai's predictions are never wrong. Surely he's just messing with him?

"I thought you'd look at it and laugh. I didn't think it would upset you…"

Dazai hangs his head, feeling a hot wash of shame overtake him.

Chuuya throws up his eyebrows. He can't recall a single time he's seen Dazai look so dejected.

"O-Osamu, I—" Chuuya puts the brownie down and takes Dazai's hands. "I'm not upset. I just…wasn't expecting that. I thought you were past this kind of juvenility."

Dazai looks up at Chuuya. "Oh, Chuuya…you should know by now that I'll never grow up."

Dazai smiles and chuckles a little, suddenly looking much less ashamed. Chuuya smiles and cups Dazai's cheeks. "There we go, that's what I like to see."

He pulls Dazai in for a sweet but deep kiss, holding Dazai tight. Dazai starts licking at Chuuya's lips, to which Chuuya fights back until their tongues tangle together, and Dazai starts making soft noises.

The noises are Chuuya's cue to pull away before Dazai gets too into the kiss. Chuuya flicks his tongue to break the strand of saliva connecting the two of them, pulling a whimper from Dazai and then a chuckle from himself.

"Mmm…" Dazai murmurs, taking deep breaths to calm himself. "You taste like chocolate."

"Ah! That's right!" Chuuya exclaims in response, completely shattering Dazai's sweet haze. He pats Dazai's shoulders to further achieve that. He thinks it's lovely what an effect he has on his lover, but now, he thinks, is not the time for Dazai to demonstrate what he had put on that brownie. "I made you some Valentine's chocolates!"

Dazai springs into action, instantly forgiving Chuuya for spoiling his libido. "Chocolates?! Gimme gimme!"

Chuuya can't help but chuckle at Dazai's cuteness. His juvenility indeed will never falter. He hands Dazai the plate of chocolates he prepared. "There are of course more for you, these are just what you can have now. Don't you want these to last you awhile?"

Dazai nods, just wanting to agree with Chuuya so he can eat the chocolates.

Chuuya motions towards the plate. "What are you waiting for? Dig in."

Dazai immediately starts stuffing his face with chocolate, making happy sounds as he eats the homemade treats. 

Chuuya takes a step back, watching Dazai eagerly eat the sweets, smiling and chuckling. He thinks it's sweet that Dazai is so excited by the chocolate—even if Dazai has no manners while eating it.

"Alright, Osamu, that's enough. I don't want you finishing your plate if you're gonna be so messy."

He takes the plate from Dazai, causing Dazai to whine and reach for it.

"You just proved my point. It's chocolate, not life-saving medicine." He puts the plate down and blocks the way. "No more for now. You need to relax, honey. Now, wash your hands and face. You look like a slob."

Dazai huffs. "Chuuya's so mean…" he whispers, but he goes to the sink anyway to wash up.

Chuuya picks up the crude brownie Dazai purchased for him, ignoring the letters. He takes a piece of it and puts it in his mouth. What he thought was frosting on top was actually just tempered chocolate.

And it's delicious.

Of course Dazai picked out Chuuya's favorite flavor. They both know each other so well.

Chuuya looks up from his brownie and sees Dazai nice and clean, eyeing the candy. Of course he is, the greedy bastard. Chuuya chuckles to himself and swallows the brownie.

"You want another one, don't you?"

Dazai looks up from the counter and at Chuuya, blushing a bit. His fingers gently dance along the counter and he nods.

Chuuya rolls his eyes. "You're lucky I'm so whipped for you. Alright, you can have one more. But—"

Chuuya picks up one of the chocolates and holds it between his fingers, an all-knowing, salacious grin on his lips. It makes Dazai's heart throb.

"—we have to share."

Chuuya puts the chocolate in between his teeth and beckons Dazai over with one finger. As if Dazai were a puppet and Chuuya's finger was the string manipulating him, he instantly flocks over to him and puts his hands on his shoulders.

Dazai leans in, and instead of taking the chocolate as "promised," he connects their lips, taking the chocolate from Chuuya's mouth and swallowing it without even tasting it. He doesn't even care that he didn't get to appreciate it. He'd much rather appreciate the delectable taste of Chuuya's lips.

Dazai clings tightly onto Chuuya, kissing him hard, yet sweetly. Chuuya puts a hand on Dazai's thigh and holds his leg, dipping him and licking Dazai's lips as if asking for entrance. Dazai quickly parts his lips and lets Chuuya's tongue in, whimpering at the wonderful feeling. He didn't care much for kissing before he and Chuuya got together, but now, he doesn't think he can ever get enough of it.

"Mm, so…" Chuuya murmurs lowly against Dazai's lips. "I know you…that brownie makes me think you have another gift in store for me…am I right?"

Dazai takes a deep breath and wraps his arms around Chuuya's neck. "Mhm…of course I did…"

"Of course you did…would you like to show me?"

"Mmm…" Dazai trembles a little as Chuuya nibbles at his bottom lip playfully. "Can we…just keep kissing for now?"

"Oh, Osamu…" Chuuya purrs like a smitten star of a '50s romance movie. "Of course we can."

Chuuya dips Dazai even lower—a bit too low, as Dazai crumbles to the ground, clinging to Chuuya, bringing them both to the floor.

They stare at each other, a bit surprised by what just happened, then start laughing.

"Hehehe, Chuuya got a bit overzealous there," Dazai teases breathlessly, playing with a tendril of auburn upon Chuuya's head. His face is red and he's breathing heavily. A state Chuuya finds stunning.

"Heh, I guess I did."

Chuuya pushes Dazai onto the floor, laying on top of him. He brushes Dazai's bangs out of his eyes, admiring Dazai for all he is.

"I love you, Osamu."

Dazai puts his hands on Chuuya's head, losing his fingers in Chuuya's hair. "Mmm…I love you too, Chuuya…"

Chuuya leans all the way in, and connects their lips once more, kissing Dazai oh so sweetly, like they hadn't seen each other in years.

"Happy Valentine's Day, indeed…"
