"Tell me your weak spot," Mei demanded one night with a straight face.
"Eh?" Yuzu vocalized intelligently, hand frozen in the middle of turning a page in her beauty magazine.
"Your sensitive spot," Mei asked again with a patient tone, adjusting her reading glasses on her nose. She was seated at her desk, tucked in the corner of her room, with a pen in her hand as she worked on student council paperwork. Though she was no longer working, since she had turned around in her seat to ask Yuzu that question.
"My what?" Yuzu questioned with furrowed brows, not understanding what the other girl was getting at.
Mei regarded the blonde for a moment, sitting cross-legged atop their bed and dressed in a ridiculous (adorable?) pink onesie. She turned back around to her work. "Forget it."
She heard Yuzu give a start behind her. "Hey! What did you mean? You mean where I'm ticklish or something?" The blonde eagerly fished for further conversation from the usually quiet sibling. Mei tried and failed to focus on the papers before her, much like the past few minutes. Her mind kept wandering to other distracting topics, such as the one she was now being confronted about.
"No," Mei answered, facing Yuzu in her chair once again. "I was curious to know if you have any… weaknesses."
"Weaknesses?" Yuzu echoed with a tilt of her head.
"Physically," Mei tried to elaborate. Seeing as how Yuzu's gaze was not coming up with anything, Mei tried to explain further, gesturing to her ear in what she hoped was a clear message. "I just thought that since you know about mine, I should know yours as well."
It was clear Yuzu finally understood when her green eyes widened and her cheeks lit up as her gaze lingered on Mei's ear. "Ohhh." The blonde's voice was just shy of a squeak and she tore her eyes away. "Wh-why do you ask?"
'Because I just spent the last few minutes wondering how fast I can get you naked, panting, and squirming under me while I-' "Reasons," Mei responded with a calm mask of indifference. Though her actions belied her expression, the pen in her hand clicked in preparation to write any forthcoming information on a piece of paper.
Yuzu narrowed her eyes at the younger girl, crossing her arms in front of her chest as she sat up straighter. Her cheeks warmed even as she tried to put her confidence to good use. "Shouldn't you figure that out yourself?"
Mei raised an eyebrow at her, the blonde failing to hold eye contact after just a few seconds. Her embarrassment was starting to infect Mei, who swallowed slowly. "Do you want me to?"
Yuzu's fingers gripped the hood of her onesie and pulled it over her face to hide how red and exposed she felt. "Y-Yeah," Yuzu said in a quietly rough voice that made Mei shift in her seat. "It's not like I know…"
Mei unconsciously licked her lips as she removed her reading glasses. "I suppose it's worth looking into…"
Yuzu peeked out from her hoodie to give Mei a mild glare for continuing with her vaguely disinterested tone of voice. Mei's expression softened and she gave Yuzu a small seductive smile as she stood up, pen and paper in her hand. "I'll take some notes."
The next day Himeko was going through the paperwork Mei handed off to her that morning, and she came across an odd scrap of paper. It appeared to be a list of some kind, and Himeko held it up to discern the handwriting. She eventually recognized it as Mei's, though it was much sloppier than usual, as if she had been in a great hurry to scribble these words down.
Curiosity piqued, Himeko started reading out loud. "Back of the knee… inner thigh… left butt cheek?" The last item was underline three times, and Himeko frowned in confusion. "What kind of list is this?!" She read on, eyebrows furrowing more with every random body part listed until she came across the last item which was circled a few times. "Neck?"
"Excuse me."
Himeko nearly jumped straight out of her skin when Mei's voice addressed her from behind.
Mei eyed the piece of paper clutched in Himeko's hand. "I believe I accidentally displaced that with the work I gave you." Mei held out her hand expectantly, eyes not quite meeting her friends.
"Ah, no problem!" Himeko hastily returned the list to Mei, who carefully folded it up and placed it in her bag. Himeko's curiosity got the better of her. "May I ask what kind of list that was?"
The tips of Mei's ears went pink. "Just some important research."
