It was a hot day at True Cross Academy and Rin was stuck in his dorm room while his younger twin brother went on an assignment. Rin wanted to cool himself down and with the huge supply of vanilla ice cream he has in the freezer; he thought he could make a good milkshake out of it.

If only he could find the blender...

Suddenly, a voice from the other side of the front door crept up.

"Um, Rin? Yuki? Anyone home?"

Rin stopped at his search and ran to the door, knowing who the voice belonged to. He open the door to see a sweaty Shiemi, wearing her school uniform. The sweat dampened her white shirt a bit, making her breasts more prominent. Rin couldn't help but the stare at her for moment.

"Rin, why are you staring at me?"

Rin quickly snapped out of his thoughts and back to his attention to what Shiemi was saying. "Oh sorry! I was just...I don't know what I was doing."

Shiemi giggled at Rin's statement, giving him a reassuring smile. "Don't worry about. Anyway, can I come in? It's sort of hot out here."

"Of course! Make yourself comfortable!" Rin blurted out.

Rin ran back to the kitchen to continue for his search for the blender while Shiemi quietly followed him. She looked around and saw the mess Rin made. There were clean dishes, bowls, and other kitchen utensils all over the floors and counters.

"What are you doing? Your kitchen is a mess."

Rin answered her while opening the last cupboard. "Trying to find my...Oh, there it is!"

Rin took out the rarely used blender and placed it on a uncluttered counter, plugging it in the socket behind it. Shiemi just stared at him in curiosity, while he took out a tub of vanilla ice cream, a bucket of ice and A jug of milk from the fridge. Then Rin turned around and turned his attention to her.

"I was going to make a milkshake for myself but I was wondering...", he trailed off, scratching his hair while he felt his cheek burning. "You wanna share it with me?"

Shiemi nodded and started to blush a little. "Sure Rin, but I never had one before."

Rin couldn't help but smile at his blonde friend. "I'm sure you're gonna like it!"

Rin poured the shake into a plastic cup and inserted two straws for both him and Shiemi. He picked it up and placed it on the table where Shiemi was already sitting. He sat across from her and gave her a nod. "Go ahead, try it."

Shiemi leaned over the milkshake and sipped through one of the straws. She couldn't believe the delicious flavor of vanilla in her mouth. She sipped some more and started to feel refreshed of the cold drink. But the sensation ended when her head started to throb in pain.

"Ahh! That hurts!" She yelped while putting a hand on her forehead.

"It's just a brain freeze," Rin said calmly. "It will go away soon."

Eventually, Shiemi's head stopped hurting and the two of them went back to drinking the shake. Rin looked at the blonde as she enjoyed the drink and his cheeks starting to go red. He didn't want this moment to end.

But his fear came true when the front door opened and footsteps came towards the table. Both Rin and Shiemi turned their attention to the figure in front of them.

"Welcome home Yuki!" Shiemi greeted the young man.

Rin's expression went from disappointment to fear when Yukio asked:

"What are you guys doing?"
