"You can start by assigning an unknown variable to this problem..."
"This problem..."
"Whoa~ Give me a break!"
Ritsu Tainaka rolled in through the doorway and looked up to see Luo Yu standing in front of her.
"Again and again... Can you keep it down for once?"
Luo Yu immediately clamped his right hand over Ritsu Tainaka's head.
"Dazed, dazed. Sumimasen! I won't do it again, let go of my head!"
Ritsu Tainaka kept struggling.
"Enough clowning around. Come in. But keep it down, okay?"
In the end, Luo Yu still let Ritsu Tainaka in.
After that, everyone settled down and studied quietly.
Before they knew it, noon had arrived.
"Is it already this late?" Luo Yu checked the time and asked the girls, "Have you figured out lunch?"
"It's fine, it's fine. Yui Hirasawa's younger sister will make lunch."
Yui Hirasawa waved her hand, her words full of trust in her younger sister.
Relying on her little sister!
The girls looked at Yui Hirasawa in disbelief.
Yui Hirasawa's younger sister, you really had it rough.
"I'll go help with lunch. There are so many of us, Yui Hirasawa's younger sister can't handle it alone."
Luo Yu stood up and prepared to head for the kitchen.
Ritsu Tainaka said, "Luo Yu, are you going to cook? I remember you saying you were really good at it, right?"
"You can look forward to it."
With that, Luo Yu left the room.
"Luo Luo's cookies were so delicious." Remembering those tasty cookies, Yui Hirasawa swallowed. "Then Luo Luo's cooking must be delicious too, right?"
The other three girls nodded in agreement, eagerly anticipating what kind of delicious food Luo Yu would make.
In the kitchen, Yui Hirasawa's younger sister was already preparing lunch.
Seeing Luo Yu arrive, Yui Hirasawa's younger sister politely asked, "Senior, what is it? Do you need something?"
Luo Yu said, "No, I just came to help you make lunch."
"How could that be okay? You're a guest, Senior. How could I let a guest cook?"
"Come on, there are so many of us. You can't manage it all by yourself, can you? Besides, next year you'll be my junior. Juniors should listen to their seniors."
"Ah~ Senior is so sneaky, using that as a reason."
Then the two looked at each other and suddenly burst into laughter.
"You're just like my sister said, Senior. You're a very interesting person."
"Aren't you the same? Other than your looks, you and your sister are completely different. You're so capable—you look more like the older sister."
"I have to take care of my sister, after all."
"That's true. You have to take care of that Yui, after all."
Then Yui Hirasawa's younger sister helped Luo Yu tie on an apron.
"Then I'll be counting on you, Senior!"
Looking at the smiling Yui Hirasawa's younger sister before him, Luo Yu smiled as well. "Then look forward to it, my little junior!"
After that, the two began making lunch.
While washing rice, Yui Hirasawa's younger sister asked Luo Yu, "Senior, can you cook? If not, just help me out."
Luo Yu opened the refrigerator and began picking ingredients as he replied.
"I can cook a little. Everyday dishes aren't a problem. We can each make a few dishes later—that should be enough for everyone."
Still, he hadn't expected the ingredients in this refrigerator to be perfect for making those familiar home-style dishes. Luo Yu silently thought as he looked through the fridge.
"Senior, what are you going to make?" Yui Hirasawa's younger sister asked Luo Yu.
Luo Yu was washing the ingredients. Hearing the question, he tilted his head and said to Yui Hirasawa's younger sister, "Want to guess?"
Everyone Was Nervous
"Want to guess?"
Hearing that question, Yui Hirasawa's younger sister looked at the ingredients Luo Yu was washing, but she still couldn't guess what he was planning to make.
"Can't guess? Then you'll find out once I'm done."
After washing the ingredients, Luo Yu lit the stove and prepared to start cooking.
As Luo Yu's dishes were completed one after another, Yui Hirasawa's younger sister's expression shifted from calm to puzzled, from puzzled to astonished, and finally from astonished back to calm.
"Whew, finished."
Luo Yu wiped away sweat that didn't exist from his forehead.
Looking at the several exquisite dishes before her, each complete in color, aroma, and taste, Yui Hirasawa's younger sister couldn't help asking Luo Yu, "Senior, this is what you meant by only knowing a little cooking?"
"Yeah, just a little."
Luo Yu looked at his level-5 cooking and made a classic gesture with his thumb and index finger.
"Senior, you aren't making fun of me, are you?"
"How could I? Yui Hirasawa's younger sister is so cute. How could I make fun of you?"
"C-Cute..."
Yui Hirasawa's younger sister covered her face with both hands and turned her back to Luo Yu.
Only after quite a while did Yui Hirasawa's younger sister calm down.
Turning back around, Yui Hirasawa's younger sister looked Luo Yu straight in the eyes and said firmly, "Senior Luo Yu! Can I learn cooking from you?"
Looking at the girl's determined gaze, Luo Yu smiled and answered.
"Of course. A senior can't refuse a request from such a cute junior."
Yui Hirasawa's younger sister looked extremely happy at that answer. "Thank you, Senior!"
"All right, don't get too excited. Go call them over to eat."
Not long after, everyone was seated at the dining table.
"Hahaha, chicken soup's here!"
Luo Yu carried the final bowl of soup to the table.
"The dishes are all here. Why isn't anyone eating?"
"We were waiting for you, of course. Also..."
Ritsu Tainaka explained, then pointed at the soup Luo Yu had just brought over.
"What chicken soup? Isn't that tomato and egg soup?"
"Sorry, that scene just made me blurt out that line."
Tch, times like this are always the worst. No one can ever get the reference. What weird stuff has gotten mixed into my DNA?
"Anyway, let's eat first."
As soon as he said that, everyone started eating.
"Delicious!" Yui Hirasawa's eyes lit up. "It's different from what Yui Hirasawa's younger sister makes—this is even better! Luo Luo, did you make all these dishes?"
"I made most of them. Yui Hirasawa's younger sister made two dishes too."
"You're so good at cooking, Luo Yu." Ritsu Tainaka swallowed the food in her mouth. "Why not just have you cook for us from now on?"
"In your dreams!" Luo Yu rolled his eyes. "Don't think you can use me as free labor. I'll cook when I feel like it. Any other time, forget it!"
"Aww~"
"Hm? This dish..." Mio Akiyama picked up a piece and tasted it. "It isn't as delicious as the others, but it's still very good."
"That one? Yui Hirasawa's younger sister made that one. What do you think? Not bad, right?"
Seeing this, Luo Yu explained from the side.
"Isn't this pretty good, Yui Hirasawa's younger sister?" Mio Akiyama praised her.
"Not really. It's only because Senior helped me. I learned so much while cooking with him."
Yui Hirasawa's younger sister glanced at Luo Yu, then spoke with an embarrassed expression.
Luo Yu said to Yui Hirasawa's younger sister, "That's because you have talent. I'm sure it won't be long before you're just as good as me."
Yui Hirasawa's gaze moved back and forth between the two of them.
"Luo Luo, did you and Yui Hirasawa's younger sister suddenly become really close?"
Hearing that, Luo Yu and Yui Hirasawa's younger sister looked at each other, then both laughed.
Luo Yu smiled. "Is that so? Then Yui Hirasawa's younger sister might as well become my little sister. I've always wanted a little sister as capable as Yui Hirasawa's younger sister."
"Ah~ Luo Yu, you're so sneaky. I want Yui Hirasawa's younger sister as my little sister too," Ritsu Tainaka chimed in.
Mio Akiyama said, "If possible, Yui Hirasawa's younger sister, could you become my little sister?"
Tsumugi Kotobuki said, "My family is lacking a capable little sister too."
Yui Hirasawa immediately hugged Yui Hirasawa's younger sister.
"I'm not giving Yui Hirasawa's younger sister to any of you."
After saying that, Yui Hirasawa looked pitifully at Yui Hirasawa's younger sister. "You won't leave me, right?"
Yui Hirasawa's younger sister patted Yui Hirasawa's head and said, "Yes, yes. I won't leave you, Sister."
"Really?"
"Really."
"You won't go to someone else's house and become their little sister?"
"I won't."
So who exactly was the older sister here?!
Watching the scene before them, everyone complained inwardly.
After lunch, everyone resumed studying.
To everyone's relief, a certain someone behaved herself all afternoon and didn't disrupt their study progress.
"You got so many right. You'll definitely pass the retest tomorrow."
After checking the test Yui Hirasawa had completed, Luo Yu said affirmatively.
Yui Hirasawa said, "Yeah! Thank you, Luo Luo, and Mio and Tsumu-tsumu too. Thank you for coming to tutor me."
"If that's the case, we should probably get going."
Mio Akiyama stood up to pack her things, then realized someone was missing.
"Where's Ritsu? Where did Ritsu go?"
Then everyone found Ritsu Tainaka in the living room, playing video games with Yui Hirasawa's younger sister.
Ritsu, you're playing games again? Why don't you take a break?
Luo Yu said, "No wonder it was so quiet this afternoon. So she came out here to play games."
