Tsuna x Reader: Jealousy, it's a first

    It had been about three months ever since you and Tsuna started going out together. You kept it a secret from most of your friends until the end of your first month, it had been quite a shocker for most, except for Reborn who had claimed that he knew it the entire time. Gokudera interrogated you at once, asking how you ended up dating the tenth when the two of you barely talked to each other in class. It was true that both you and Tsuna never had the chance to talk at school, but that was only because Tsuna had insisted.

    "Hey, Tsuna." You were walking home side by side, fingers interlocked with each other and you knew Tsuna was nervous since his fingers were shaking lightly. 

    "Y-Yes?"

    "We've been dating for three months now, why're you still nervous?" You chuckled, trying to calm the fidgety brunette.

    "W-Well...I just can't get used to it." Tsuna mumbled, running a hand sheepishly across his spiky brown hair. Your footsteps sounded against the cold asphalt surface as you both walked to Tsuna's home for a Vongola meeting. You knew about the Vongola and the fact that Tsuna was the Decimo, it surprised you at first but it wasn't as though you'd break up with him just because of a little secret. The Tsuna you knew was kind and sweet, and in your opinion, Tsuna would make a fine mafia boss, although you did end up in a small argument with said teen when he found out that Reborn told you.

    "So, why did Reborn suddenly call for a meeting?" Tsuna sighed at this then slumped his shoulders. "I'm sure it's just something crazy Reborn thought up of again." 

    "You think so?" You were both nearing the decimo's home when you heard a familiar voice call out to the both of you.

    "____! Sawada-dono!" You whipped your head towards the direction of the voice, and a smile swept across your features.

    "Basil! Long time no see!" You greeted, letting go of Tsuna's hand momentarily to greet the blue-eyed teen. Tsuna smiled a bit then greeted Basil as well.

    "Hast thou been well?" Basil asked, smiling at you brightly as he waited for you to reply. You had first met Basil when you were at the convenience store and had trouble reaching for something in one of the top shelves, you remembered how surprised you were when Reborn introduced him to you when you visited Tsuna for a school assignment. His japanese was a bit difficult to understand, but it was just one of the many few reasons why you thought he was fun to talk to.

    "I've been good lately, thanks for asking." You giggled. Tsuna brought the two of you inside the house, though it took a while since you all had to dodge Lambo and Ipin as they played a friendly game of chase (still friendly, since Lambo decided to keep away his grenades). Basil successfully maneuvered the two of you into the messy home, picking up a few stuff here and there. "Giannini-dono is here, I apologize I have not cleaned thy's home." He spoke to Tsuna in a slightly troubled tone. You've always liked how polite the young teen was. 

    "No really, don't worry about it. I bet Lambo and Ipin were just playing a bit too rough today." Tsuna laughs nervously.

    "Stupid Tsuna. This is why you're always getting pushed around." Reborn pops out of nowhere and, with a giant mallet, hits Tsuna with great force. Sending the brunette collapsed onto the floor with a strangled cry.

    "Tsuna!" You panic, running over to your boyfriend before Reborn had stopped you mid-way.

    "I'm taking this idiot with me ____. You can wait for us to finish in the living room with Basil." As Reborn dragged Tsuna off by the collar, you could have sworn that you heard Gokudera and Yamamoto's voice calling out to their friend in a worry. Sighing lightly, you turned to face Basil who was busy picking up the toys that Lambo had left out in the open. 

    "Here, let me help." You offered with a smile before bending down to pick up whatever was left.

    "I cannot possibly allow a woman to-" Basil retorted.

    "Don't worry. I want to help." In the end Basil could only let you do as you wish. You grabbed the littered toys and put them away before trotting into the kitchen to help Tsuna's mom to make the snacks. 

-----------------

    "How was the meeting with Reborn?" You asked Tsuna as you plopped down onto the seat next to him. "It was...fine." He replied a bit unsure. Basil sat close beside you, something that Tsuna noticed with ease. He had nothing against Basil, that much he knew, but he couldn't ignore the soft tugs on his chest when Basil started talking to you. 

    "Tomorrow we're going to have an activity in the mountains. Make sure to assemble before dawn! We're going to go hiking." Reborn announced happily before the crowd of people dispersed and went their separate ways as they went home. You scrambled to gather your shoes and bag in a hurry before grabbing the door and pushing it open.

    "Would the miss want thy company in returning home?" Basil stepped out from inside the living room and out the hall with a wide smile on his face. 

    "Actually, let me. Mom might need your help with things Basil." Tsuna stuttered, his words coming off rushed as he grabbed his shoes and slipped them on before the blonde could beat him to it. "I'll be back soon! Let's go ____!" Tsuna grabbed your hand then fled, leaving a rather confused Basil staring at the now empty doorway.

    The streets were empty when you had stepped out of Tsuna's gates, the moon hung high in the dark sky, covered in a thin blanket of clouds and glittering stars. You giggled when Tsuna sighed. 

    "I-Is something wrong, ____?"

    "You know that Basil and I are just friends right?"

    gulp

    "O-Of course I d-do!" Tsuna laughed nervously, running his hands through his gravity-defying hair.

    "Then don't get jealous, Tsuna." You laughed heartily as his face erupted into a million shades. You were new to this kind of relationship and so was he. This was just the first of the many experiences you'd get to have, what made it more special was because it was with him.
