Sakuto (Yamashita Tomohisa) who witnessed the kiss between Haruka (Kuriyama Chiaki) and Hachisuka (Ishimaru Kanji) called Rio (Tanimura Mizuki) and spent the night together. The next day, Haruka who was called by Hachisuka in his office, matches the awkward face of Sakuto. Hachisuka wants Haruka to tell Sakuto the address of Sakuto's mother Madoka (Kusakari Tamiyo). Thinking "The operation was successful. When she sees myself now, mother will be delighted." Sakuto wants to meet Madoka so he requested Hachisuka. In that case, Haruka said why don't they go together so she can show him around but Sakuto said he's fine alone. On the other hand, hearing about Sakuto and Rio spending the night together, Yanagawa (Kubota Masataka) and Hiyama (Kudo Asuka) are surprised. Mai (Omasa Aya) who heard about Rio's sickness from her father (Nakahara Takeo), talks to Rio frankly about this. That time, Haruka visits Takebe (Hagiwara Masato) at Dream Flower Service. She came to install a studying device to be used while sleeping at Sakuto's dormitory. Hearing from Haruka that today Sakuto went to see his mother alone, Takebe's expression completely changed. What in the world is Takebe worried about? At that moment, Sakuto rings the intercom at Madoka's house...
