In a crossover anime, the only way to become stronger is by marrying a wife.

The last time Tsukikawa Shu and the others went out together after school, they ran into two girls, Orimoto Kaori and Nakamachi Chika. These two girls not only interrupted other people's conversations, but also openly mocked the cookies made by Yuigahama Yui.

Afterwards, he was scolded by Yukino Yukinoshita and Hiiragi Tsukikawa before leaving in a huff.

Now, facing Tsukikawa Shuu's still icy gaze, she dared not look him in the eye, so she turned her gaze to Yuigahama Yui and Yukino Yukinoshita.

We don't know how much personal grudge is involved, but it certainly is.

For example, the other party didn't even look at it. They just took the proposal, flipped through it a few times out of boredom, put it down, and started pointing out its flaws.

"Yeah, it's not luxurious enough at all. What kind of writing is this?"

Chika Nakamachi also put down her proposal at this moment.

Starting with Kaori Orimoto and Chika Nakamachi, members of the student council of Kaiken General High School also voiced their objections.

"I think... it's really not that great."

"Yes, yes, isn't this proposal too detailed? It's really affecting everyone's creativity."

“I think creativity is the most important thing. For example, the color and number of lights on a Christmas tree don’t need to be specified. We should give full play to our initiative, so that it will look more natural.”

……

As the group opposite them chattered away, countless flaws were immediately pointed out in Yukino Yukinoshita's proposal.

Isshiki Iroha remained seated, awkwardly smiling throughout. She was completely helpless at this moment, as she was not good at dealing with such things.

As for the other student council members, since the president hadn't taken any action, they dared not speak up on their own and remained silent as if trembling with fear.

As a result, the winds of change were consistently one-sided, and Yukino Yukinoshita's proposal was criticized to the point of being riddled with flaws.

"What you're saying won't affect the overall execution of the Christmas festival, will it?" Yukino Yukinoshita frowned.

That's why she doesn't like sharing leadership with others; who can't find fault?

"NONONO, Yukinoshita-kun."

Yu Sheng shook his head and rubbed his hands together in the air. "Personal opinions are bound to be biased. The opinions of everyone are the truth. We should come up with a plan that meets the opinions of everyone. That is the best choice."

"My proposal is at least very practical. If you have any complaints, just revise and supplement it." Yukino Yukinoshita was too lazy to waste words with the other party and directly stated her attitude.

"Yes! Yes! Yukinoshita's opinion is also worth exploring, and we will incorporate it into the meeting."

Yu Sheng fiddled with her hands. "So, let me continue the discussion! Let's come up with the best solution!"

“I already said that my plan is the best…” Yukino Yukinoshita’s tone left no room for argument.

Given the situation at Seaside High School, Yukino Yukinoshita isn't sure she can come up with a better solution.

Based on their utterly disastrous, unrealistic planning outline, and this meeting that's all fault-finding but no better solutions.

It's unlikely that discussing this with this group will lead to any better progress.

"Yukinoshita's opinion is also worth keeping, and we will consider your opinion when we discuss it as a group," Tamaki said with his usual smiling face.

"So, what's your specific plan?" Yukino Yukinoshita's tone was icy cold.

“A proposal made hastily is bound to be bad, just like Yukino's proposal. It may seem usable, but if we spend more time discussing it, we can make it better, right?”

Yu Sheng smiled and said, "Respecting everyone's opinions and coming up with a plan that satisfies everyone is the best plan that combines the wisdom of all of us, isn't it?"

With the other person's restless hands, which looked like they were making a Rasengan, Yukino Yukinoshita felt her blood pressure rising rapidly.

Tsukikawa Shu watched all of this quietly.

He listened to the entire conversation between Yukino Yukinoshita and Tamahane, and just found it quite funny.

Business decision-making often follows the principle of satisfaction, not the principle of optimality. The principle of optimality is often irrational; it's impossible to achieve the best solution for every condition in a decision-making process.

This theory applies to everything.

The so-called principle of satisfaction means that the actions taken are exactly enough to achieve the goal. This avoids wasting resources on thankless tasks.

For example, a college student who is just giving up should be happy if they can pass the final exam; any more than that would be a waste, instead of trying to achieve a perfect score.

Similarly, for this Christmas gathering, all that's needed is a plan that satisfies all the visitors to the Christmas festival overall. The marginal efficiency of the optimal plan will continuously decrease, making it a completely thankless and arduous task.

But with an added prerequisite: the best decision that takes into account the opinions of all parties.

This makes it even more impossible for such a thing to exist.

Moreover, these guys can't even define what the "best solution" is.

"Also, we need to consider the participation of these children. Look, I've already called them over. We can't just send them away now, can we?"

Yu Sheng fiddled with her hands, smiling amiably.

"You shouldn't have involved irrelevant people in the first place!"

Yukino Yukinoshita was very angry about the other party's attitude.

"NO, Yukinoshita-san, this is about pooling collective wisdom and strength. You can't underestimate them just because they're elementary school students!" The other person's words were firm and resolute.

Yukino Yukinoshita looked back. The group of little girls were still sitting in their original seats, curiously watching what was happening, blinking their eyes as if they didn't know what had happened.

"..."

With this excuse, Yukino Yukinoshita had no choice but to return to her seat.

She never expected that her painstakingly prepared proposal would be immediately rejected as worthless.

But... we really can't send Tsurumi Rumi and the others away right now.

Since we can't get rid of them, we have no choice but to revise the plan.

"We've already shared the grand design with everyone. Today, let's discuss the more creative aspects. It needs to have our own style, but also a Christmas theme!"

As President Yu Sheng rubbed his hands together with an almost magical motion, the members of the student council of Haibin Comprehensive High School began to speak enthusiastically.

“I think it would be great to hold a classical music concert at the Christmas festival,” suggested a boy wearing glasses.

"Ah! I agree! I agree!" Orimoto Kaori raised her hand high.

“Yes, yes! Sure, we can join the discussion.” Yu Sheng nodded.

The words "Classical Music Concert" were written on the blackboard.

“No, no, I think we should switch to jazz instead of classical music,” another person said.

"Yes! Yes!" Kaori Orimoto shouted.

“Yes, yes! I also really like jazz, let’s add it to the discussion.” Yu Sheng nodded again.

Another topic for discussion has been added to the blackboard.

“I think if we’re going to include jazz, we should add some music from younger generations,” the third person suggested.

“Yes, yes! After all, we are dealing with young students, so we can join the discussion.” Yu Sheng nodded again.

A new topic has appeared on the blackboard: young jazz music.

"I think it would be nice to rent a large screen and show some touching films."

"I agree! I agree!" Kaori Orimoto exclaimed excitedly.

"Yes, you can join the discussion." Yu Sheng seemed to be listening very attentively and even nodded.

"I think we could put up a long banner, and in addition to writing slogans, we could also have everyone sign it."

“Yes, yes!” Orimoto Kaori agreed.

“We can also make some large posters, and make them more detailed. Let’s start with twenty and paste them in various corners and sections.”

“Not bad, not bad!” Orimoto Kaori said.

"Yes, yes! I can consider it." Yu Sheng nodded again.

……

Each suggestion was written down on the blackboard.

Rumi Tsurumi and the others who had been invited sat to the side, looking at each other, unsure of what to do.

At this point, none of the proposed solutions were ones in which they could participate.

"Hey, how about we ask the teacher what we should do?"

A little girl mentioned it.

"I don't want to go..." someone answered timidly.

"I'll go ask someone else."

Rumi Tsurumi also noticed the problem at this moment.

She walked over to Iroha Iroha.

“What should we do?” she asked.

"Haha... well, let's talk about that after the meeting." Iroha Isshiki said somewhat awkwardly.

Everyone was annoyed by the endless discussions of the Seaside Comprehensive High School Student Council, but they endured it out of politeness.

“You can make some origami first; these are things you’ll need when decorating the Christmas tree,” Yukino Yukinoshita said.

“Okay.” Rumi Tsurumi nodded.

But at this stage, we can only arrange some peripheral matters; the main activities are still under discussion.
