It had been almost half an hour since the class observation began.
　When the teacher asks for a show of hands to see who can solve the math problems written on the blackboard, the students raise their hands enthusiastically to show their families that they are doing well.

　Amana was the only one who didn't raise her hand and kept her face down.

　Her expression is far different from that of her other classmates, and she has a dark and somber look on her face.
　Hasumi and the others looked at her with concern, but they couldn't talk to her during class.

　The teacher, who is teaching the class, also notices, but decides that she can't let the progress of the class slow down, so she presses the chalk to the blackboard and writes up the questions, killing her feelings.



　Once the feeling had sunk in, he slowly fell into the crucible of his thoughts.　　
　

(Don't blame it on Onii-san!　(Because they're so sweet!)

　In the event that you're in a situation where you're in a situation where you don't have the time to spend with yourself even when you're at work, you'll be able to judge the presence of Wa, who cherishes time with you even when you're at work, as someone who is trustworthy in Tenna's mind, even if not as trustworthy as his mother, Tenri.
　It's a good thing that I don't understand why Tenri sees him as an enemy to such an extent.

　That's why he thought that he had offended her by becoming friends with Wa.

　In reality, the reason for this is that the train was stopped because of a fatal accident that occurred at a station outside the city, but it would be absurd to ask Tenna, who has no way of knowing that, to guess.

(Pardon me, that's a lot of work, isn't it?　(Then I don't blame you for not being able to do this...)

　In the end, that's where I ended up with the answer, based on my past experience.
　He was resigned to the idea that it was inevitable that adults, not just Tenashi, would be busy with their work.

　By believing that, Tenna swallowed her own frustration.
　But it doesn't disappear as it is digested.
　Like a pile of dust, little by little it will accumulate.

''Well then, let's take this issue--''
""Yes!"

　In the class that was going on regardless of Tenna's state of mind, the teacher left the students to answer the questions.
　The children cheerfully raised their hands and tried to show their sunny appearance to their parents who had come to visit.

　Only Tenna was the only one who kept her face down.

　When it was time to choose one of the students who raised their hands first.....

　─ ─ The door at the back of the classroom was opened with a rattle.

　The sudden loud noise caused everyone in the classroom to roll their eyes in surprise and stare in that direction.
　There was a woman standing there, her shoulders swaying widely.

　Her dark brown hair was stuck to her forehead from sweating, as if she had arrived in a great hurry, and her hair was disheveled to the point that it could not be called unkempt in a flattering way.
　However, regardless of the gaze of those around her, as soon as she made eye contact with the girl in the classroom and made a face of relief, her expression, which was imbued with frustration, was transformed into an admiringly cheerful one.

　Then, as she adjusted her breath and body language, she slowly opened her mouth while blushing, partly because she was aware that she was receiving all the gazes of the surroundings.

''Jyu, I'm sorry for interrupting your class. I'm Nantenna's mother, and after finishing a busy errand, I belatedly came to visit my daughter's class.
"!

　When the woman - Nantenashi says her name, the parents who have come to visit the school let out a breath of admiration from her appearance.
　Even if more than half of the class time has already passed, they are trying to burn the sight of their children's hard work into their eyes.
　He admired the sight of them.

　It's a good idea to have a good idea of what you're going to do with it.

　─ ─ I'm here to watch you properly.

''Huh!''

　With her silent inspirations, Tenna's depressed feelings up until now have vanished from her mind nicely.
　Her Ruri eyes, like her mother's, regained their usual brilliance to meet the expectations of the person she loves.

　And then Tenna.....


''Yes!
Let's get Ms. Minami to solve it.

　He raised his hand cheerfully and came forward as a respondent himself.
　The teacher, who had been watching the series of exchanges, nominated Tenna with a smiling expression on her face.

　Standing up from her seat and approaching the blackboard, she held the chalk in her right hand and raised her heels to write the answer to the question.

''Yes, that's the correct answer.''
Yes!

　From an adult's point of view, it was a problem that could be solved with one hand, but the person who solved it was really proud of it.
　Tenna turned her big smile on Tenashi.

　The daughter's sunny appearance that she had always wanted to see, Tenashi was also caught up in it and had a smile on her face.

　─ ─ Well done.

　Since it's only in class, Tenashi praises that with a mouthful of praise.

''Ehehe!''

　Receiving those words, Tenna decided on a peace sign with a more radiant smile.

　And so the class proceeded in an orderly fashion, and at the time when the class was about to end in five minutes, the teacher clasped his hands together and gathered his gaze.

''Okay then, everyone!　Let's give your mom and dad a gift for coming to school today.
""Yes!"

　All the parents nodded their heads at the sudden revelation of the present.
　After all, that was not mentioned in the printout with the date and time of the class visit.
　Naturally, Amanashi felt the same way.

　On the contrary, the children who had been preparing ahead of time got up from their seats, took out a sheet of paper from their desks, and then brought it to their families at the back of the room.　

'Three, two, one, yes!'
"'Ooh, ooh, ooh, ooh!　Thanks for everything!

　When the teacher gave the signal, the children handed a piece of paper in their hands, face down, in unison.
　It was a picture drawn by colored pencils.

　Although they were poorly drawn due to their young age, I could tell that they were all drawings of my parents.
　And the most important thing in this moment is the feeling of gratitude for the gift, along with the words.
　Some of them were so moved to tears when their own children, who they had raised with so much love and care, expressed their gratitude in both words and pictures.

Yes, Mommy!
Thank you, Tenna.

　Of course, Tenashi, who received the painting from Tenna, was also holding back tears on the verge.
　Being able to be here with the help of Wa, Tenna's hard work and the gratitude that was handed to her...they filled her heart with happiness.

　Their first class visit ended amicably in this way.
