Yuuko was lying on the couch, her eyes not drawn to her open shounen-ai manga but instead drawn to her younger brother who was lying on the ground, looking quite intently at a page on his shoujo manga. Something was up with him, especially considering how he has been looking at that one single page for several minutes.

She was starting to get a little curious about what has captivated her brother so much, and that curiosity led her to actually asking her brother. "Hideyoshi, you've been staring at that page for several minutes, is something up?"

"Sis, have you ever fallen in love?" He suddenly asked, his question surprising Yuuko.

She blinked, wondering where this had come from. "No... I haven't." She wondered why her little brother had suddenly asked something like that, and it didn't take her long to reach a conclusion. "Wait, Hideyoshi, are you...?"

Hideyoshi looked up at her, a somber smile on his face as he looked into her eyes. "Yeah, sis." He said, answering her unspoken question. "I've fallen in love with a girl."

A wave of fleeting shock fell over Yuuko, stunning her for just a moment until she was able to regain her composure. "W-well, tell me about her." She said softly, her mind racing as she tried to figure out just who her brother could have possibly fallen for.

She couldn't even think of one girl.

Hideyoshi looked away, back to his manga. "She is someone... special, very special." He told her softly, a light blush spreading across his cheeks.

Someone special? Well, of course the girl he is in love would be someone special to him. "Is she smart? Athletic?" Yuuko pressed, wanting to know just who this girl is.
Hideyoshi nodded, opening his mouth to speak a moment later. "She's very smart and even more athletic."

Well that ruled out quite a few girls she knew, including the only two girls in her little brother's class. So, someone who is very smart and athletic? Aiko kind of fit that description, but there's no way her brother would fall for someone like her. "Can she cook?"
"She's an excellent cook." Hideyoshi said, his cheeks growing a little redder.

So, along with being smart and athletic, this girl was also a cook? Definitely not Mizuki. Getting nowhere with the kind of questions she was asking, Yuuko decided to ask something different. "How long have you known her?"
There was a short pause before he answered. "A very long time now, sis."

She was stumped. "Arrgh! Just tell me already!" Yuuko exclaimed, closing her own manga and leaning down towards Hideyoshi.

He looked back at her, a somber look in his eyes as he smiled softly. "She is... someone I can't be with, sis..." With that said, he stood up, closing his manga. "I better go fix dinner now, sis. We're having sukiyaki tonight."

As Hideyoshi walked away, Yuuko looked back at him, her determination growing. Hideyoshi, I'm going to find out who you're in love with.
