The waiting time is a bit long

　　Asada House.

　　Rui closed the book in her hands, got up from the bed and left the room.

　　The house is empty, and Hina heads out for an interview, while Shinichi is at cram school.

　　The calm atmosphere, although she didn't hate it, she didn't like it either.

　　"5:40 p.m.... After dinner, they should be home by now, right?"

　　While muttering, Rui took out her phone and sent a message asking her older sister to come back for an early dinner.

　　Just as she was about to tell Shinichi as well, she suddenly remembered that she didn't have his contact information.

"He has to come back."

　　"He said the tamagoyaki was a bit sweet, so let's make the dish without adding sugar. He didn't eat much fried food yesterday, maybe he likes something lighter."

　　Thinking of what to do for dinner, Rui passed by Shinichi's bedroom door, and suddenly stopped, with a glint of unhappiness in her eyes, she kicked the door with her white foot.

　　"The door is actually locked... I want to read that book..."

　　Rui was displeased, she used to be able to enter if she wanted to, but now the door was locked.

　　"Well, why not just cook a meal full of sugar, the kind that will cause post-meal diabetes."

　　Rui came to the kitchen, put on her apron, and started cooking.

　　As the spatula and kitchen utensils collided, the sound of the door opening was heard, and a familiar female voice full of vitality immediately sounded.

　　"Wow, smells so good~ Rui's skills are still as good as ever~"

　　"Stop flattering, wash your hands and get ready to eat." Rui brought the last dish to the table, and took off her apron.

　　Hurriedly running to the toilet, then to the living room, Hina saw a dazzling dish on the table. She sat excitedly at the dining table without even changing into her professional attire.

　　"Why is dinner so extravagant today! Did something happy happen?"

　　Rui said indifferently: "That fellow criticized yesterday's cooking in the morning, so let him look good."

　　This is partly why.

　　"As for the other part... If he wanted to see him say the food was delicious," Rui didn't need to tell Hina.

　　After Rui finished speaking, she sat down on a chair, picked up a book and started reading.

　　Hina was about to move her chopsticks.

　　"Rui, you don't want to eat?"

　　Rui looked up said: "That guy hasn't come back yet."

　　"Ah, right..." Hina stuck out her tongue, and was a little embarrassed, "I'm so used to eating with Rui, and I forgot that Shinichi-kun was around..."

　　Speaking of this, she frowned: "But...He hasn't come home this late, can he eat out?"

　　The hand that was turning the book stopped, Rui sighed softly, "I was just thinking about this question... But Hina Nee-san do you have a way to contact him?"

　　 Hina shook her head.

　　"No! I just wanted to ask Rui. You communicate with him more often than I do. Didn't you two exchange contact information? Whether it's email or LINE."

　　 Rui said helplessly, "I don't think it's necessary... After all, I rarely exchange contact information with people..."

　　The two sisters glanced at each other, Hina holding chopsticks in her hand.

　　"Then… Shall we wait for him to come back to eat?"

　　Right after she finished speaking, there was a loud hungry sound in Hina's stomach. Rui looked at her.

　　"Okay, let's eat first. After all, the two of us can't eat all this food alone."

　　If he didn't eat, the leftovers should be enough for Shinichi to eat. At worst, she could cook more.

　　If Shinichi has dinner... Make it for lunch tomorrow.

　　Isn't he going to attend cram school? Coincidentally, the bento had run out.

　　Rui and Hina clasped their hands together, their voices sounding weak in this empty and quiet house.

　　"Ittadakimasu."

　　"Hmm~ Although the taste is a bit bland, it's still delicious~"

　　"Ah, that's good."

　　20 minutes later.

　　 Hina has gone upstairs. After Rui washed the dishes, she sat down at the dining table and read a book.

　　40 minutes later.

　　Rui stood at the living room door looking at the dark entrance.

　　After an unknown amount of time, she shook her head and resumed reading.

　　The seats get a little cold.

　　60 minutes later.

　　Taking the food to reheat, Rui took out her cell phone and looked at the time on it, opened and closed several web pages, curling her hair boredly.

　　Putting her cell phone aside, she hugged her knees, looking at the night view outside the window, absentmindedly thinking about something.

　　80 minutes later.

　　The third time the food was reheated, she tasted it and it didn't taste good.

　　Without hesitation, Rui immediately threw away all the dishes that had lost their original deliciousness, then re-cooked a new table of dishes for one person.

　　As for whether to say it is a waste of materials... She doesn't care, she just goes out to buy it tomorrow when it runs out.

　　After wrapping all the hot dishes in plastic wrap, she went upstairs and came downstairs with a new book.

　　Rui faced the living room door, then realized she was reading a book.

　　The waiting time is a bit long.

　　It was hard getting out of class and ending cram school that day.

　　Walking along the orange-smeared street, the three of them left school together and walked towards the family restaurant that had just opened in April.

　　According to Fumino, she often went there to eat, it was cheap and delicious.

　　At first they were going to Rizu's house, but considering it was difficult to concentrate on studying there, and Rizu had to help out when the shop was busy, they chose to go to a family restaurant for dinner.

　　After eating, the "review meeting" will immediately begin.

　　"The speech is too fast and I don't understand? Preview well first. You shouldn't be lazy in this area. People can speak 100% in an hour, but you can only understand 20%. Then the remaining 80% or more must be read first. Once you understand it, you can verify it during the talk, and you can have time to note down what you don't understand..."

　　"Furuhashi, your memory is very good. If you can't quickly understand the problem, it's best to memorize how to solve the problem first. If you don't have time to think about how to solve the problem, just memorize the formula used. And the point is, just remember what the lecturer said. If you pass, then whatever your knowledge, you're very quick to copy notes…"

　　The three of them were engrossed in absorbing the results of that day's study in the family dining room without interruption.

　　It was almost 8:30 before they finally stopped and calmed their tense minds and bodies.

　　"Ha~ This is the most tiring summer vacation I've ever had..."

　　Fumino leaned against the back of the chair, head drooping weakly, feeling as if her soul was about to fly out of her mouth.

　　"I feel the same way... My brain is going to explode..."

　　Rizu lay down on the table, her eyes filled with tears.

　　"It just so happens that there's no class tomorrow, so make preparations for when you get back. I'm sure you'll get used to it soon."

　　After a few words of encouragement, Shinichi started packing his things, but his brows furrowed.

　　He didn't know why, but he had an inexplicable feeling that he had forgotten something.
