"You should start crying over the stress of planning our wedding," Kiyoomi says, lips curved into a teasing smile.

"Oh, I won't be the only one crying. I'll make sure you cry during the process and at the altar," Atsumu teases back before pulling Kiyoomi for a kiss.

— END

Atsumu pinches Kiyoomi's cheek, "you're so smooth everything you say and do just sweeps me off my feet,"

Kiyoomi smirks, "I know," he whispers before kissing Atsumu. "So, starting today, you should stop crying over our hypothetical break up when it's raining."

"I didn't expect our conversation to go the way it did. But I'm glad you're such a drama queen." Kiyoomi laughs, admiring Atsumu's hand before kissing it, "it gave me the perfect opportunity to propose."

Kiyoomi chuckles, "I didn't expect this too. I had a grand plan, y'know? I was going to take you to our favorite restaurant and then take you to Tokyo Metropolitan Gymnasium and propose there. But my guts told me to do it today," he explains as he slips the ring on Atsumu's hand.

"How did you know I wanted this one?" Atsumu asks, wiping his tears.

"I have sources," Kiyoomi shrugs, "now, what's your answer?"

Atsumu sniffles and gives Kiyoomi his trembling hands, "God, I can't believe this is how you decided to propose."

Atsumu pulls away and stares at the box, "it's not my fault you're too slow,"

"Well, Miya Atsumu, will you marry me?" Kiyoomi kneels on the group and opens the box, showing the ring Atsumu had been eyeing for the past year.

Atsumu drops his jaw at the sight.

"Shit! Oh my god! Kiyoomi, yes!" He yells and hugs Kiyoomi as tightly as he can.

Tears quickly fall from his eyes as he continues to whisper 'yes' into Kiyoomi's ear.

"You didn't even give me the chance to ask," Kiyoomi says.

Atsumu crosses his arms, "that's brave coming from someone who doesn't have a ring." He says in the sassiest tone he can muster.

"How are you so sure I don't have one?" Kiyoomi asks, smirking, before reaching into his pocket to pull out a ring box.

Atsumu reaches for Kiyoomi's hair and ruffles it, "I'm sorry. I'll stop. I'll cry over our hypothetical wedding instead." He teases.

Kiyoomi pulls away and stares Atsumu in the eyes, "who said it's a hypothetical?"

Atsumu nods. Kiyoomi rolls his eyes and buries his face into Atsumu's neck.

"I'm glad you trust me. But I don't feel comfortable knowing you still imagine me leaving you." Kiyoomi admits.

"Because no matter what happens, you're love for me will stronger than anything," Atsumu kisses Kiyoomi's fingers and turns to smile at him.

"So, what you're saying is that you're secure enough in the relationship to be okay with imagining me leaving you?" Kiyoomi asks.

"But you know, I'm aware that day will never come." Atsumu says, taking Kiyoomi's hand in his to play with Kiyoomi's fingers. "I know you'll never leave me no matter how much I annoy you or push your buttons."

A fond smile graces Atsumu's lips as he continues.

He rests his chin on Atsumu's shoulder, eyes looking out the window as he accompanies Atsumu.

"Well, the rain is making me feel melancholic. So, I thought it'll be a good idea to listen to sad music while looking out the window," Atsumu explains, leaning against Kiyoomi.

Kiyoomi continues to play with Atsumu's cheeks for a few more minutes before letting go and kissing them.

"That's painful, Omi-kun," Atsumu says, palming his reddened cheeks.

"Serves you right." Kiyoomi responds before wrapping his arms around Atsumu's waist.

Kiyoomi pinches Atsumu's cheeks and pulls on them, "a few seconds ago you were crying because of an imagined break-up. Now, you're in the mood to tease me, huh?"

Atsumu chuckles before grabbing Kiyoomi's wrists to stop him from pulling on his cheeks, but Kiyoomi doesn't budge.

"Just my ass? You'll only stay because of my ass? That's so superficial, Kiyoomi. You're hurting my poor fragile heart," Atsumu teased, feigning hurt.

"I don't know why you love torturing yourself by imaging things that'll never happen." Kiyoomi whispers as his hand rubs comforting circles on Atsumu's waist, "as annoying as you are, I'm never leaving your ass,"

Atsumu turns to him, eyes watery, "you broke up with me," he whispers, voice shaky from being on the verge of crying.

Kiyoomi only sighs and hugs Atsumu. It's not his first rodeo comforting Atsumu from his imagined heartbreak.
