"What are you talking about! Commanding! Where do the student council presidents need to do these things! Hillu quickly stepped forward, and then shouted at the two girls who were at least a head taller than herself.

"Tsk, who is this person, is it your friend?"

"It's a freshman, it's so rude, just treat our third-grade seniors like this." The two girls glanced at each other, and the disdain in their eyes was fully revealed.

"You guys!" Ciellu was angry.

"It's not... It's just a school girl I just met.,By the way, I helped clean up.。 Song said softly.

"Oh... It seems that he is also a very helpful person~ Then the work of the toilet will be handed over to you, let's go first~" The two girls giggled and left.

"Damn!" Ciellu stomped her foot angrily.

"Let's go." Sota picked up the mop and walked in the direction of the toilet.

"Hey, hey! You're really going to the toilet to clean up! The cleaning aunt will be in charge of handling it, we just need to study hard, and cleaning here will already help everyone. Hillu stopped.

"Hillu?" Doubts could be heard in the distance.

"Huh? Yukino..."I looked up and found that at the end of the bookshelf was my wife, Yukino, who was looking at me with a look of shock and some unhappiness.

"What's wrong? Is there something going on? "Quickly put the mop to the side, ran to my wife Yukino's side, and hugged my wife Yukino's arm, although I don't know why my wife Yukino has a black gas-like substance behind her, but there is a voice in the bottom of Hill Lu's heart warning himself:

"Hurry up and find Yukino! Otherwise, it's over! ”

"It's okay... Why is Hillu with this senpai? My wife Yukino saw Hirlu running over and hugging her arm, and the black qi behind her dissipated a little, and then her expression softened, and she returned to her weak appearance, and asked cautiously.

“... Ah, I'm helping my sister clean the library. Hillu breathed a sigh of relief, then replied.

"Do you need my help?" asked my wife, Yukino.

"Well, Xue Nai will come along." Thinking that it would not be good to let Yukino stand alone on the side, Shirlu shoved her mop into my wife Yukino's hand, and said:

"I'll go to the bathroom and get the tools again, Yukino and Sister Kana will mop this place up together!" Then I ran to the bathroom.

"Hello... Senpai" Yukino said hello.

"Hello." Sono nodded.

"May I ask Senior Sister, what do you think of Xiaolu..."Xue Nai asked cautiously.

"Good guys." Soda replied.

"Oh..."Hearing this answer, Yukino nodded reassuringly, and then went about his job.

"I'm back!" Worried that the two of them would be particularly awkward together, so Hillu got the tools and trotted all the way back, only to find that the two got along with each other unexpectedly, which made Hillu a little stunned.

"Well, Hillu, we've cleaned this floor." My wife, Yukino, nodded.

"There's a first floor that needs to be cleaned... Once you're done, you'll be fine. Kana looked up and said.

"The first floor...."Hillu was stunned, the area of the first floor is the largest in the library, and judging from the current cleaning speed of the three people, it will take half an hour to clean up the whole first time.

"If you have something, you can go first, these things don't need ordinary students to do." Song shook his head, then reached out to take away the cleaning tools from the hands of the two of them.

"Huh... I can't let my senior sister do so many things alone..."Hillu quickly hugged the tool in her hand and said resolutely.

The three of them went to the first floor with cleaning tools.

"Xiao Song~ I'm here to help with the work again~" The librarian grandmother I met in class before came over and asked kindly.

"Yes." Sono nodded.

"Are these two your friends? It looks like a strange face, is it a new student? The old grandmother glanced at Sillu and my wife, Yukino, who were standing behind the music, and asked.

"Well, it's a freshman." Hillu nodded.

"Xiao Yue is a good boy, don't bully her, if you let me know that you are bullying her, I will definitely teach you a good lesson!" It's funny that the old grandmother is threatening, but it doesn't seem to be a joke to see the old grandmother's serious appearance, so Hill Lu said with a straight face:

"We know, we really see the music as friends."

"That's fine." The old woman nodded.

"By the way, mother-in-law, what's your name?"

"Just call me Granny Tea." Granny Tea replied with a smile.

"I'm going to clean up first." Soda said softly, then turned back and walked towards the edge of the first floor.

“... Granny Tea, Sister So, does she often come here to clean? Hillu asked, seeing that Kana was walking away.

"Alas... Yes, the students in the performance class always bullied her, and I don't know how the parents of the performance taught the little play, and they would still be stupid to believe those words at this age, alas. Granny Tea sighed.

"Why did the school leaders choose Sister Song as the president of the student union? Sister Song has such a good temper, it is better to be the vice president. Hillu wondered.

"Because of Xiao Song's talent, she is the only talent in the school at present who is a super rare student, plus she is good at talking, so she was given the position of president of the student union by the school leaders, Xiao Song has been like this for three years, so she should be used to it." Granny Tea sighed deeply again.

"Has Senior Sister Song's temper always been like this?" Hillu was a little confused.

"Well, most people think that Yue is a cold child, in fact, she is just too introverted and doesn't express her feelings very much, but children at this age don't pay much attention to the feelings of others, plus Song is the only super rare talent student in the school, and she is jealous of others, so she has no friends."

"How can this be..."Hillu shook her head sadly, her temper reminded her of herself when she was a child, and it was also because her temper was too introverted, she didn't have any friends, and she didn't have anyone at home, and she once liked to harm herself... to attract the attention of others, so is this also the case with Senior Sister Song?

"Cough..."Yukino suddenly coughed twice.

"What's wrong?" Hillu looked back.

"No... It's nothing... I'm going to help! Yukino quickly turned her head and hurried away.

"Huh?" Scratching her hair suspiciously, Hillu turned around and said to Granny Tea:

"I'm going to help, too! Goodbye to Granny Tea! Then he chased after the two who had gone first.

"Young man... It's the way I felt back then. Granny Tea smiled and watched the three young people leave one after another, revealing an emotional expression.

"I was... Ahem, nostalgia is old, rest go, rest go. ”
