Time always passes very quickly when there is something to do, for example, like now, Rintaro forgot the time in the process of constantly drawing questions and answering questions, until the door of the classroom was opened, and Rintaro, who was about to explain to Seori Katase what characteristics she could use to speed up the question just now, turned his head and glanced at it, and the person who opened the door without saying hello was Hazuki Katase.

"Sister? What are you doing here? Didn't you go back? Hoshiri Katase looked a little confused.

Katase Hazuki's expression looked a little helpless: "Although it's a good thing to study seriously, you should also pay attention to the time." Look what time it is. ”

Rintaro picked up the mobile phone he put next to him and looked at it, there was an email, and the time was already more than 5:40 in the afternoon, Rintaro not only did not leave work early, but even worked overtime for more than ten minutes, Rintaro couldn't accept it.

"Where has the time gone?" He muttered to himself in confusion, and got the roll of Katase Hazuki's eyes.

Katase Hazuki walked over and put the umbrella in his hand on the table, and Rintaro saw that she seemed to have brought a lot of umbrellas, and Rintaro blindly guessed that one of them was for himself.

"Isn't it over on your side?" Katase Hazuki asked.

"It can be disbanded at any time, this question...... Forget it, I won't talk about this question, it's all the same thing anyway. Rin Taro put down Hoshiri Katase's scratch paper: "It's almost time to change it back, you guys go first, I'll clean up this place before I go out." ”

"I'm here to help, too." Hoshiri Katase stood up, then looked at his sister and said, "Sister, wait for me." ”

Rintaro didn't refuse this kind of help, and he and Hoshiri Katase simply cleaned the used place, and it took less than a minute for the three of them to leave the club classroom together. The umbrella that was just put on the table was indeed prepared for Rintaro, and in the afternoon, the umbrella that Katase Seori handed to Katase Hazuki was finally returned to his hands.

It's still raining outside the school building, but it's better than in the afternoon, it's not that big, and there is no problem with an umbrella. Maybe it's because of the rain, and now the school is very quiet, and there are no people in sight, so the figure of a student who is obviously not his own school walking towards him and others is also very conspicuous.

Rintaro was originally going to leave directly after saying goodbye to the Katase sisters, but when he quickly recognized which person was holding an umbrella in his hand and holding an umbrella that Rintaro was very familiar with in the other hand was Rai Katase, Rintaro thought of two things.

First of all, I didn't expect her to have a little conscience.

The second thing is that something is going to happen.

The first thing is because Rintaro didn't expect Katase Yorai to think of bringing an umbrella to pick her up and go back with her, after all, she was holding her own umbrella in her hand, which shouldn't be wrong. The second thing...... Rintaro had already begun to feel beside him, and the cold air emanating from Katase Hazuki's body had spread to his side.

It's much colder than when it's raining.

Rai Katase also seemed a little surprised, but her face quickly changed to a smile and she walked over to this side.

"So you have umbrellas, and I thought that if you didn't bring umbrellas, this umbrella might be able to be used." Yorai Katase walked in front of the three of them and shrugged his shoulders: "In that case, do you want to go home together?" ”

"No, I don't." Katase Hazuki snorted with a cold face, and then pulled Hoshiri Katase, who was about to say hello to her eldest sister, and left.

This is no longer an ordinary sisterly contradiction, this is simply a refusal to dialogue. Rintaro looked at Rai Katase, and couldn't figure out what this woman with a smile on her face had done to her sister to make Katase Hazuki so angry. It wasn't until the two of them left the school and disappeared from Rintaro's view that Rintaro turned his head to look at Rai Katase, whose smile seemed to be a little helpless.

"What the hell did you do to be hated like this?" Rintaro asked curiously, Katase Yorai turned his head to look at Rintaro, puffing out his mouth: "Rintaro, if you don't reply to my message, forget it, you actually let me run into Xiao Hazuki, you are too much." Did you do it on purpose? ”

"Replying to your message?" Rintaro thought about it, and suddenly remembered the email he had seen when he was still looking at the time on it, took out his mobile phone and looked at it, and found that the sender was Yori Kasese, and opened it to take a look.

[Rintaro, it's raining outside, I'm at a department store, do you need me to come and pick you up?] ]

"In the afternoon, I was in class, so I muted my phone...... "Rintaro explained, "but thank you." ”

"Is it just a thank you? Nothing more practical? Yorai Katase still had a puffed face.

Rin Taro took his umbrella from her hand expressionlessly, opened it, and then handed over the umbrella that Katase Hazuki brought to him: "Here, Hazuki-san, it should be your umbrella, right?" ”

Katase Yorai looked at the umbrella in Rintaro's hand and nodded: "Yes, it's indeed our family's umbrella, but I think it's better for you to take it first, and then return it directly to Xiao Hayue when you come to school tomorrow." ”

Rintaro thinks the biggest reason is the relationship between them. Put the umbrella that has not yet been opened into his school bag, Rintaro held his umbrella and walked from the shelter of the teaching building to the shelter of the teaching building, and Katase Yorai also hurriedly followed.

"Tell me, what's going on in your family?" Rintaro gets straight to the point.

"It's not too much of a problem, it's just that Xiao Yeyue has reached the rebellious stage. In a few years, our relationship will be repaired naturally! Katase Yorai's face was full of smiles.

She probably wasn't prepared to talk about it. Rintaro doesn't care, it's just a casual question anyway.

"Gone." Rintaro walked quietly in front, just wanting to hurry back to his room and stay. By the time he realized that his "gone" didn't seem to be taken for granted, Katase had already walked to the side.

…… Forget it, it's pretty much the same anyway.

As he walked, Rai Katase asked him how Rintaro was teaching today, and Rintaro thought about it and introduced her in very concise vocabulary: "Your sister is very good." ”

The smile on Yorai Katase's face cracked into a question mark.
