Guess

"So, why did you call me here, Kimu-san?"

The question left Takumi's mouth. The curly teenage boy looked at me expressionlessly standing right in front of the guardrail.

I took a deep breath, putting on a serious face.

"So you accuse me of being the culprit?" asked Takumi flatly.

Bingo! I haven't accused him yet, but he already knows I'm going to say he did it.

Stupid! Or was it on purpose? Who knows.

I nodded.

"You are the culprit, Kaboshi Takumi."

He looked at me defiantly. Slowly, both hands lifted up to fold in front of the chest.

"How could I drop Tamaki? I wasn't on the roof when Tamaki fell. After all, isn't it Kenkyo-senpai, your nephew who knocked down Tamaki?"

I winced. There seemed to be something wrong with what he just said. Nephew he said? Do we both really look like Uncle and nephew? Oh, it's okay. It's not bad either, the important thing is that they don't think Kenkyo is my daughter.

"Isn't that right? Tamaki fell because of Kenkyo-senpai?" he said again.

"No." I argued. "Tamaki-san fell off the roof by herself ... Oh no, I was wrong. She fell because of an invisible hand that knocked her off the roof with your trick." I glared at him.

"What do you mean?"

I smiled happily, "Glasses are the main point of this trick. I'm right, right?"

Takumi chose to remain silent.

"In Tamaki's room, there is a letter written in Kenkyo's name telling him to go to the roof. It's likely that Tamaki is interested in going there, because the perpetrator who sent it uses Kenkyo's name."

He's still silent. He confronts the official detective. Moreover, he brought Kenkyo. Really stupid, right? I checked everything. I already knew, and there was no reason he could deny it. He thought I wouldn't go all the way to the root? Very stupid!

"Coincidentally, ah no! According to your plan, Kenkyo went up on the roof, because you know it's a habit when I come to visit on Thursday, then Kenkyo will go to the roof to pick up my coat which he dried at night.

"Okay, going back to Tamaki, naturally he must be looking for Kenkyo who hasn't come yet. She must have been around looking for Kenkyo. And when Tamaki was in front of the guardrail, Tamaki saw someone waving at her. Because of her blind eyes far away, Tamaki doesn't even know who is waving at her, whether it's Kenkyo or who. That's why the girl wears glasses to see the person waving at her."

"Then what's weird?" cut Takumi quickly.

I saw his face changed slightly made me smile.

"That's the main point. Look, what if we change the lenses of Tamaki's glasses that don't match her vision? Tamaki will lose her balance because her blurry vision makes her head spin."
