Nanahara Takeshi quickly walked into the living room, turned on the TV, and the VCR. The VCR began to play footage from Sugita Sayoko's birthday last year. Nanahara Takeshi pressed the remote control to rewind the scene back to when Sugita Mai "interviewed" Sugita Yukio in the study.
In the footage, Sugita Yukio was reading a book in the study. When he heard Sugita Mai ask, "Father, what birthday present have you prepared for mother?" he closed the book, took off his glasses, and lightly biting the arm of the glasses, he revealed a smile, as if pondering whether to spoil the surprise for his lively adopted daughter.
At this point, Nanahara Takeshi pressed the pause button, and Kiyomi Liuli also realized what was happening, exclaiming in surprise, "The poison was smeared on the arm of the glasses?"
