I feel sad because I'm already delayed with this fic. It was supposed to be published before Christmas. Oh well. This is another pairing that I wanted to explore. Because it's a cross-over fic, it will be very light and discreet. But I hope you like this one. Btw, I'm only adding one more chapter before I close this series of one-shots. I will try to post it on Christmas day itself. Thanks!

Falling for You

By Slavedriver2008

"We're home," Kinimoto Toya called out in his deep voice. "You can use my spare slippers while you're here." Hongou Yui nodded and slipped her feet on the big pair, leaving her shoes on the ledge. She was staying over the Kinimoto residence because they have some dissertation paper due tomorrow that needs finishing tonight.

"Welcome home, Toya-nii!" a girl with short brown hair greeted them. "It's nice to meet you, Yui-nee-sama," she said happily, though they were not introduced yet. "I'm Sakura. I'm so excited to meet you, nii-chan seldom bring girls home—"

Touya pinched the girl's ear and Sakura winced. "You're too noisy, monster." He walked inside the house, leaving them at the door.

"It's Toya's turn to cook tonight. You should take a bath first." The girl pulled her inside the house. "Dad! I'm bringing Yui-nee to my room!" Yui followed the girl. She was supposed to share the room with Toya's sister, though she doubted if they'll sleep at all.

Sakura was a freshman in junior high and she's pretty. She looked like a good girl too. Her father was Yui's professor in anthropology last term. At some point, she developed a crush for him. Toya was also a medical student like herself and they were paired for this project. After 15 minutes, she walked out of the bathroom, freshly-washed and wrapped in only a towel. Sakura blushed when she saw her form.

"You're really very pretty, Yui-nee. Do you like my brother?" she asked and Yui raised an eyebrow. Like Toya? He was like a rock, always quiet in class. She actually prefered men who were more expressive, like his bestfriend Tsukishiro Yukito. She was always paired with Yukito and this was the first time she got paired with the dark-haired heartthrob.

"Like?"

"Yes! Toya-nii doesn't have a girlfriend. I don't remember him dating anyone even in high school," Sakura explained. How can someone like Toya have a girlfriend? He seemed to belong in the densest guy category. He was literally not her type of guy. She was over the mysterious brooding ones—she doesn't want another Nakago. "What do you think of him, nee-san?"

"He seems like a good person…"

"That's it?" Sakura looked back with disbelief and she nodded. It was not fun being cornered by her partner's younger sister. The girl sighed and sank back on the bed. "That's sad. I think he likes you, though. He seldom—never, actually—brought a girl home."

"But it's for a project, Sakura-chan. I'm sure he wouldn't bring me here if he has a choice." Sakura frowned.

"Well, he looked excited when he told us you're sleeping over. He even agreed to do my chores for the week so I'll let you sleep in my room…" Sakura said and Yui laughed lightly. "I thought I'd finally have a nee-san."

"I'm sure your brother will bring home a girl he loves one of these days. But even so, I can be your nee-san. I don't have any siblings so I don't mind," she said, smiling softly at the girl.

"But still, it would be nice if you're Toya-nii's girlfriend—" the door banged open and Yui gasped, clutching the towel tighter. Toya was surprised to see her but looked at her from head to foot. "Nii-chan! What are you doing here!" Toya immediately turned around. Yui wanted to faint, every part of her body was probably red from humilation.

"Dinner's served," he said stoically. "Stop asking Yui stupid things, Sakura." He spun around and immediately closed the door. Yui hurriedly put on some clothes. This was exactly what they were trying to avoid—sexual tension. It was the reason why she agreed to do their project in his house instead of her apartment. There was less chance of them doing something inappropriate. Not that Toya would be aggressive or he lacked self-control but it was better to avoid intimacy.

"I'm sorry I forgot to lock the door, nee-san… Toya-nii usually just barges in especially when it's dinnertime. I'm—"

"It's okay. It's actually my fault. I should have dressed up right after I walked out of the bathroom," Yui sighed after getting dressed. She was wearing a white shirt and a green shorts. She put on a hoodie and turned to the apologetic little girl. "Should we go down now?" The girl nodded and led the way downstairs. Yui was still struggling with Toya's slippers, they were way too big for her. She'll surely trip before the night end.

"Good evening, Yui." Prof Kinimoto smiled and she blushed. She bowed down and greeted the two. Sakura sat down beside her father and Yui sat beside Toya in the table. He was not looking her way and was focusing on the food. She was sitting across the professor and her heart was thumping loudly. "I heard the department looks forward to your dissertation paper, Yui-san. My friends from the faculty said many good things about you," the professor noted and Yui looked down, flushed.

Toya looked at her from the sides of his eyes, he'll probably realize sooner or later that she's crushing on his father. "I…Arigatou gozaimasu, Kinimoto-sensei," she said softly.

The man laughed and offered her food. Soon enough, they were talking about the latest developments of his project. He also asked what her parents are doing and she said her parents were doing a program in South Africa and will be spending the holidays in Cape Town. The professor asked her to spend the holidays with them but she turned it down. Her grandparents were expecting her over the holidays and she's going straight to Kyoto after the project.

The dinner went on in a cheery mood and Yui was briefly envious because Toya goes home to a warm happy family every night. The food was good too, she could never imagine Toya could cook well. After dinner, the professor offered desserts but Toya insisted they eat it while doing the paper.

Toya took the tray and asked her to lead the way toward the living room. Yui was at the door when she slipped, Toya managed to catch her but they both fell hard on the floor, the tray crashing on them. Yui's eyes widened when she realized his lips were on hers. Her heart beat wildly and her face grew warm. He gently moved away. The world stopped moving and being under him suddenly felt like the most perfect place to be stuck.

"We're under the mistletoe…" he said softly, as if meaning to explain why they did what they did. There was a slight blush on his cheeks. She nodded, still gaping. Kissing him was… wow. They were not much movements but the feel of his mouth sent bolts of electricity throughout her body. Not one of her former boyfriends made her feel so blissful with just one chaste kiss. He smelled of after-shave lotion and musk. It was a normal homey smell but it made him suddenly very alluring. His lips were still parted and she briefly debated with herself whether to kiss him again or not. Yui blinked countless times. What was she thinking? This was Kinimoto Toya, the last man she'd date in the world. He laughed lightly and her heart palpitated more.

"Yui-nee-san!" Sakura called loudly and the connection snapped. He slowly moved away and offered a hand. She took it, cheeks still flushed from their brief encounter. The world seemed different afterwards. She noticed all the small details about him, like the fact that she barely reached his shoulders, and that a broad chest and long arms could easily cover her for an embrace.

Yui ran her fingers through her long blonde hair and was briefly surprised when some cream stuck into it. Now she has to take a bath again. She looked at him from the sides of her eyes and realized the cake was also smudged on his shirt and hair and face. She blushed and looked away, the night was turning out weirdly. The bareness of the door surprised her, there were no mistletoe on it. She flushed harder and looked back, eyes meeting broken plates and glasses on the floor. She should go and clean it up, it was her fault anyway. She moved away and realized he was still holding her hand. She pulled it but he didn't let go. Instead, he held her tighter. He was not meeting her gaze and was still teasing his sister.

Toya laced his hand on hers. Yui turned to Sakura to see if she noticed but the girl did not. Her eyes met the professor's and he smiled knowingly. Yui looked down, embarrassed. Now she won't be able to look Toya and his family straight after this. Toya held her tighter and she looked down. A smile spread on her lips when she realized that his hands were cold but it made her warm all over.

She liked that.

A/N: This story made me almost go beyond the word count too. Ugh. Building tension in a new pairing is always very hard. But my imagination's wandering with this two. Now I feel like doing a story on them. Please do leave reviews!
