"Tsuku, go on the potty."

Tsuku pouted up at Haruhi before staring dubiously back at the toilet. It was huge! She had a special seat that the twins had bought just for her that had little steps and a small seat that went over the large toilet seat so she wouldn't fall in. "No. I don't like it."

Haruhi sighed, her patience wearing thin. For the past few months, she had been trying in vain to potty train Tsuku. Somehow, Tsuku had gotten it into her head that there was some sort of 'toilet monster' and refused to have anything to do with the toilet. "Tsuku, you're a big girl now, right?" When Tsuku nodded, Haruhi continued. "Big girls go on the potty. Only babies where diapers."

Again, Tsuku looked at the toilet. She seemed to think about it for a moment before once again shaking her head. "No!"

"No luck?" Kyoya glanced up from his laptop as Haruhi came back into the music room with Tsuku.

"No." Haruhi sighed in frustration. "She can't go into daycare until she's potty trained."

"So?" Hikaru asked from his spot on the couch. "Why does she need to go to daycare? She can just stay with us."

Haruhi put Tsuku down and watched the little girl run over to Hunny and Mori who already had a slice of cake ready for her. "She needs to play with kids her own age. It's not good for her development if she only plays with us. Especially certain members of the club." She looked pointedly between the twins and Tamaki.

Kyoya sighed and closed his laptop before standing up. He took Tsuku by the hand and led her into the bathroom, the rest of the Host Club following close in the bathroom. Kyoya ignored Tsuku's indignant yelp as he pulled her shorts and diaper off and plopped her down on top of her toilet seat. He crouched down so he was face to face with the now petulant toddler. "Tsuku, you are a big girl now and you need to go on the potty like one. Now, I know you need to go potty since you just ate. You're going to sit here until you go to…"

Everyone stood there in stunned silence, trying to process what had just happened. Tsuku had lifted both her hands while Kyoya had been speaking and promptly slapped him on both his cheeks. The smack echoed through the room as everyone waited with bated breath to see how Kyoya would react.

Kyoya touched one of his swollen red cheeks, a cold smile on his face. He stood up slowly, and…smacked Tamaki and the twins upside the head with his clipboard.

"What'd we do?" The three shouted, holding their throbbing heads.

"I would rather not raise my hand at Tsuku again if at all possible." Kyoya continued smiling. "Besides, I'm sure it's your fault somehow."

"Tsuku!" Haruhi took Tsuku's hand and lightly smacked it. "That's a no-no! We do not hit! You're being a very bad girl."

Tsuku's lower lip trembled. "You're mean! I don't like you, Mommy Haruhi!"

"That's a very mean thing to say." Haruhi said before standing up and leaving the bathroom. She sighed as she plopped down on the couch with the other Host Club sitting around her save for Mori. "I don't know what to do with her. I'm so sorry, Kyoya."

Kyoya waved his hand dismissively. "It happens."

"Maybe I shouldn't pressure her so much…" Haruhi said thoughtfully. "Maybe she's not ready to be potty trained."

"Don't give up, Haru-chan!" Hunny said, his ever bright smile present. "Tsuku-chan is just trying to assert her independence is all!"

"Where'd Mori go anyways?" Tamaki asked, looking around for the tallest Host.

"And where's Tsuku?" Kaoru piped up.

His question was answered a moment later by Tsuku running out of the bathroom, her shorts and diaper still missing. "Naked Booty Dance!" She shouted, swinging her hips from side to side.

Haruhi didn't know whether to laugh or be mortified. The twins and Hunny were howling hysterically while Tamaki squealed and shouted for Tsuku to put her clothes on. Kyoya simply rolled his eyes and went back to typing on his laptop.

Mori came out behind Tsuku, her diaper and shorts in his hands. "She went."

Tsuku didn't protest as Mori redressed her. She ran over to Haruhi and hugged her. "I sorry, Mommy Haruhi. I be good girl now. I went potty!"

Haruhi smiled and hugged Tsuku. "I'm very proud of you. You get a sticker for being such a big girl."

Tsuku's violet eyes widened in joy. "I get sticker?"

Haruhi nodded and pulled a sticker sheet out of her bag. She smiled as Tsuku squealed in delight at the pink smiley face sticker Haruhi gave her. "Now, I think you owe Kyoya-senpai an apology."

Kyoya glanced over from his laptop as Tsuku sat beside him on the couch. "Yes?"

Tsuku crawled into his lap, facing him. "I sorry. I love you, Kyoya." She kissed both of Kyoya's still red cheeks.

"Thank you." Kyoya patted Tsuku's head and resumed typing on his laptop with Tsuku still sitting in his lap.

Haruhi rolled her eyes as the first of the customers began trickling in. It was just another day in the Host Club.
