Hiroshi Yamada (Takeshi Yamada) is the manager of the Trash aquatic plant store. The business is so light that it is almost difficult to sustain. One day, a girl came to her door and asked to be a shop assistant and stayed on the spot. It was only later that Zhi Shi learned that the girl was a supermodel named Yoshio Morikawa (played by Nagaji Yoshimoto). The dull Zhi Shi was completely confused about the appearance of the ringtone and the purpose of his behavior. "Girls' behavior has a specific meaning." under the repeated hints of the bell tone, Zhi Shi finally remembered the story of 13 years ago. He, Huali and Yuji were inseparable companions, but later lost contact. As time flies, Zhi Shi was surprised and pleased to see the grown Huali reunited with him as a ringtone. One day, the news of Yuji (Takamoto Gao Shi) also came that he was injured in the hospital. After Zhishi and Hua Li went to see Youji together, Hua Li said to Zhishi that he would stay and accompany Yuji. Zhi Shi, who returned alone, was depressed and unhappy, when his father (Xiao Ri was acted the role of Wen Shi) came to visit and told him an amazing secret.
