"Where is he?" Tsuna asked Chikusa for the second time. The hat wearing man pointed to a door on the far left; Tsuna bowed and ran towards it, his towel blowing up from behind him. Noticing that the door was slightly cracked, Tsuna peered in to make sure Mukuro occupied it. What he saw was not something he was ready for.

Mukuro was in there, all right, but he was fully naked, selecting clothes to put on from his closet. Tsuna felt his face redden as he stared jealously at Mukuro's much more matured body; the raven-haired boy was lean yet muscular, and his skin was the same creamy white all over. Tsuna blushed as he noticed another much more developed aspect of Mukuro. He turned away, ashamed. He glanced back through the crack to watch the taller boy bend over and pick up his shirt which he dropped; Tsuna fully turned his body away from the door, pressing his back against the grey wall next to it.

"Oh...ohmigosh," he mental stuttered, looking down at his feet. "He's actually kinda...really...hot." Awkward pause.

"What the hell did I just think?" he whispered, putting his hand to his forehead. Suddenly, Mukuro opened the door to his room, clad in boxers and a t-shirt. He seemed surprised to see Tsuna standing there.

"M-Mukuro!" Tsuna stammered, as if the taller boy was the on at fault. "What are you doing here?"

"I was just going to the laundry room to see if my pants were washed," the raven replied. "What's your excuse?"

"Um, I was just looking for you!" Tsuna smiled. "I just wanted to thank you for what you're doing for me...Is your eye feeling better?" It was looking less red.

"Yeah. I washed it out," Mukuro said. "Hey, don't you want to borrow a t-shirt or something? It must be hard to move around in nothing but a towel."

"Um, sure. Thank you. Would you mind if I helped you with dinner afterwards? It's the least I could do."

"Yeah, okay. Here, let's find you something to wear." Tsuna blushed as Mukuro led him into his room.

"You look for a shirt while I get some pants," he ordered, walking out. Tsuna was left alone in the room.

"So, this is Mukuro's room," Tsuna thought, looking around. It was pretty dismal; the only personalized part of it seemed to be his closet. The brunet opened the closet doors wider and peered in; a varied display of green, black, red and blue shirts met his eyes. He noticed the green camouflage one that Mukuro normally wore with his school uniform. Curious, he pulled it out and slipped it on. He frowned as he looked down; the shirt almost came down to his knees , and the sleeves to his elbows. Looking in the mirror, he decided to wear it.

"I don't need pants, I guess," he thought, feeling the shirt swerve around his knees as he walked towards the door. Then, he froze.

"Ohmigosh," he thought, looking back at Mukuro's dresser. "I need underwear."

Was it okay to borrow Mukuro's underwear...? Awkwardly, Tsuna opened the dresser's first drawer to find multiple pairs of assorted boxers.

Hands trembling, he reached down to pull out a pair of tidy-whiteys. He held them at arm's length. They looked way too big. Tsuna set them aside on the bed, trying for another pair. As he peered inside, he found a black leather book labeled, "Collection of Thoughts." Curious, Tsuna opened the book to the latest entry. It read:

"Dear Diary: Today I am inviting Tsunayoshi-kun over for a sleepover. I've noticed that he is developing very well (as a Mafia Boss)." At this, Tsuna frowned. "If only he weren't so naïve...Cute kid, though."

Tsuna was interrupted by Mukuro walking into the room. Horrified, he hurriedly hid the book behind his back.

"Oh, Tsunayoshi-kun! I just realized that you need underwear, don't you?" Mukuro said, tossing a pair of pink panties over to Tsuna. "Here, these are Chrome's, but they've never been worn...Whatcha got there?"

"N-nothing!" Tsuna stammered.

"Is that...my diary?" Mukuro asked.

"N-no!" Tsuna denied, blushing. "It's, uh...my diary!" Mukuro frowned at Tsuna.

"You lie," he spat, moving closer to Tsuna. "Your diary is blue."

"What? How did you-"

"Give it to me," Mukuro demanded, holding out his hand. Trembling, Tsuna handed it over.

"I'm sorry, Mukuro-san. I was just looking for underwear..."

"You were going to wear my underwear?' Tsuna winced, blushing even more.

"N-no..." he stammered, but Mukuro grabbed his upper arm very tightly, catching the brunet's attention.

"How much did you read?" Mukuro asked, staring harshly into Tsuna's eyes. Tsuna gulped; he was already in such deep trouble that lying would just make it worse.

"Only the last bit..." he answered truthfully, squirming in Mukuro's grip. Mukuro's hand slowly dropped to his side.

"Oh, no..." the raven-haired man thought desperately. "He read...that part."

"If you want to go home, you can," he said miserably. "I understand."

Tsuna blinked. "Huh? Why would I want to go home?"

"Are you okay with what I wrote in there?" Mukuro asked.

"Uh, yeah. Why wouldn't I be?"

"It's just that, well, I didn't know you..." Mukuro cut himself off. "Well. If that's the way you want it, then let's get down to business, shall we?"

"Wait, Mukuro-san, regarding the Vongola business you wanted to talk to me about..."

"Oh, yes. I feel a lot more comfortable talking about that now."

Suddenly, Chrome walked in.

"Oh, Boss! Did my panties fit you well?" she asked.

"Sorry, Chrome, but I don't think we'll have any use for them anymore," Mukuro replied.

"Um, Mukuro-san," Tsuna cut in. "I agree with what you write in your diary, and I appreciate it, but I don't think we should act on it right now."

"I don't want to have to prove my abilities as a Mafia boss to him," he thought.

"Hmm, so he's modest," Mukuro thought to himself. "How adorable."

"Diary? What?" Chrome asked, looking over at Mukuro. Mukuro nodded, then glanced to the door and back at Chrome. Nodding back, Chrome exited.

"Oh," Mukuro then said, becoming alert. "I've got to boil the rice." And with that he, too, left. Tsuna and Mukuro's diary were left alone in the room. Tsuna peered over at it, frowning.

"Since he already know I read it...it wouldn't hurt to finish the entry, would it?" he thought, picking up up the journal and flipping open to the page he had been on. He continued reading the entry written in scrawly handwriting:

"In fact, he's so cute that I don't even know what to think anymore. And not only is he developing nicely as a mafiosi, but also as a man. Chrome agrees with me, but I don't think she's as interested..."

"Wh-what is this...?" Tsuna said aloud, the diary shaking in his hands. Appalled, he continued to read:

"This is wrong...I shouldn't be attracted to a guy, much less Sawada Tsunayoshi. But he's so cute, and his body is so lewd..."

"L-l-lewd!?" Tsuna choked out, his eyes widening. "Wh-what?"

"I don't know if it's hormones or what, but lately I've been erotic dreams about him, too," the diary went on. "I wonder if he'd let me be his first?"

After reading this, Tsuna threw the diary across the room. His heart was beating a mile a minute, and his face was very red.

"So...Mukuro-san l-likes me?" he thought, putting his hands on his cheeks. He didn't want to admit it, but somewhere inside of him he felt elated; his heart was cheering as if he had just won a competition.

"Well, he is good looking...for a guy," he thought openly, his blush deepening. "I...don't think I'd mind being..." He then fell silent.

"Ah! What the hell? Here I go thinking creepy things again..."

Then, Mukuro walked in again. "The rice is done, Tsunayoshi-kun," he said. "You look a little red...do you have a fever?" Mukuro put his hand on Tsuna's forehead.

Tsuna backed up. "I'm f-fine!" he assured him, waving his hands in front of himself.

"I should hope so," Mukuro replied. "By the way, did you ever put on those panties? Here." He picked up the underwear and gave them to Tsuna, watching as the younger boy stepped into them.

"Maybe I do have a fever," Tsuna thought. "Maybe I'm imagining all of this."

"Maybe you should rest a bit," Mukuro offered, gesturing toward the bed.

"That doesn't seem like a bad idea. Thank you," Tsuna said, sitting on the bed. Mukuro smiled.

"Dinner will be ready in five minutes," he said, heading out the door. "I can bring it to you, if you want." Tsuna watched Mukuro leave, then he realized his situation.

"Wait!" he called out. Mukuro stopped and turned around.

"Yes?" he asked, walking back over to Tsuna. Tsuna blushed, looking at the floor.

"M-Mukuro-san..." he started, swinging his feet. "Is it true? Do you really like me?" Mukuro blinked, and then he gave Tsuna the warmest smile he could, taking his hand. He bent down and kissed the boy's hand, much to Tsuna's embarrassment.

"Of course," Mukuro replied. "But, Tsunyoshi-kun, how do you feel about me?" Tsuna's face turned even redder, it that was possible.

"I...I don't know," he said, turning away. "I'm sorry." Mukuro was slowly massaging the brunet's hand in his own, staring into Tsuna's eyes. Tsuna felt compelled to tell him the whole story.

"You see, I hadn't read all of what you think I did, and I didn't know you..." he trailed off, not able to look Mukuro i the face.

"I see," the raven-haired man said, his expression blank. "Let's forget this ever happened, shall we?"

"Eh? But, wait, I-" Tsuna started, but Mukuro stood up.

"Let's go eat," he said. "Chikusa, Ken, and Chrome must be hungry."

"Mukuro-san, wait!" Tsuna said. "I think I like you!" Mukuro stopped in his tracks.

"Let's discuss this over dinner," he said. "I'll get our plates and we can eat together in here." Mukuro wordlessly walked into the kitchen, took two helpings of food, and went back to his room.

"Tsunayoshi-kun..." he began, sitting down and handing Tsuna a plate. He set up a small table in between them. "I want you to be honest with me. Do you...have feelings for me?"

"To be honest...well, I don't really know if I like you. I mean, you are, admittedly, attractive, but sometimes you scare me..."

"Scare you?"

"Well..." Tsuna started, hoping he didn't make Mukuro mad. "You're just very intimidating sometimes."

"I'm sorry," the taller man said quietly.

"Don't be sorry," Tsuna said. "It's who you are. It's not a bad thing." Smirking a bit, Mukuro picked up a spoon of rice and stuck it into Tsuna's slightly agape mouth. Embarrassed, the Vongola chewed it and swallowed.

"I don't like having my emotions toyed with, Tsunayoshi-kun," Mukuro started, putting a spoonful of rice into his own mouth. "What do you think of me?"

"W-well, I like being around you,' Tsuna admitted. "You make me worry, but you can be very thoughtful at times."

"Yes?"

"And, uh..." Tsuna continued, averting his gaze from Mukuro. "You've got a nice body." Mukuro raised an eyebrow.

"Oh?" he said, licking the spoon in his hand; watching him made Tsuna's skin crawl. "You're not so bad yourself, Tsuayoshi-kun. I like petites."

"Th-thank you...?"

"So you do openly like me?" Mukuro asked, feeding Tsuna another spoon of steaming rice.

"Well, I'm not...sure of my feelings, but I don't dislike you, if that's what you mean," Tsuna replied.

"Okay then, Tsunayoshi-kun. I won't stress you over this. How about a date tomorrow, then?"

"S-sure," Tsuna said. At least he didn't have to worry about it right now.

"Well the, Tsunayoshi-kun. I can make arrangements at a restaurant if you like."

"Um, that's okay, you don't have to-" Tsuna started, but cut himself off as he knocked into the table Mukuro had set up for their meal; his bowl of rice fell off and landed top first into his lap. "Owww!"

"Tsunayoshi-kun, are you alright?" Mukuro asked concernedly, rushing over to Tsuna. He removed the bowl and the rice from the smaller boy, setting it aside.

"I'm sorry, Mukuro-san," Tsuna said, finding himself apologizing once again. "This was your favorite shirt, wasn't it?" Mukuro smiled softly, caressing Tsuna's cheek with his hand.

"Shh, don't worry about it," he said. "Change out of it; I'll get you a new shirt." And with that, Mukuro stood up and walked over to his closet. He rummaged through his clothes, looking for a comfortable shirt. Tsuna watched him pathetically, feeling tears form in his eyes. He stripped off his wet t-shirt and set it next to him.

"All I've done is cause problems," Tsuna thought, hot tears streaming down his face.

"Here," Mukuro said, turning around and holding up a black t-shirt. Noticing that Tsuna was crying, he dropped the t-shirt and ran over to the brunet, knocking him onto his back on the bed.

"What's wrong?" he asked, staring down at Tsuna under him; his hands had trapped the smalled boy's wrists above his head.

"Nothing," Tsuna started, but he faltered as he met Mukuro's concerned gaze.

"It's just that I've been causing you so much trouble," Tsuna confessed, staring up at Mukuro.

"That isn't true," the pineapple-haired man replied, frowning. "It's not like you've been doing it on purpose." Tsuna nodded, taking a deep breath; his bare chest rose when he did so, almost touching Mukuro's. An awkward silence followed. Tsuna could feel his face burning, but to his discomfort, Mukuro looked perfectly composed.

"Tsunayoshi-kun..." the raven-haired man started, loosening his grip on Tsuna's wrists. "Can I kiss you?" Tsuna's heart skipped a beat. He watched Mukuro slowly lick his lips; the brunet's entire body began to tingle.

"I-I'm sorry, Mukuro. I d-don't think I'm ready for my first kiss," Tsuna admitted, unable to look directly at the mist guardian.

"Tch. I see," Mukuro frowned, shifting over to lie on his back next to Tsuna. The both stared at the ceiling for a moment. Mukuro then turned his head to the younger boy.

"Hey, Tsuna," he started. Tsuna blinked. Now Mukuro was just calling him "Tsuna"? No "Tsunayoshi-kun"?

"Yes?" Tsuna answered after a pause.

"Put a shirt on."

"Can do," the shorter boy replied, expressionless. He got up and picked up the black shirt from the floor. Mukuro stared still at the ceiling as Tsuna put the shirt on.

"I'm going outside," Tsuna said, coldly yet not without a hint of regret. "Thanks for, um, dinner and stuff." He paused in the doorway.

"You're welcome," Mukuro replied, still not looking at him. Tsuna stood awkwardly for a moment before stepping out.

"Well, that sucked," Mukuro thought to himself.
