S1, E4: Eri, Sakurai's ex-girlfriend from Indonesia, has come to Japan to get back together with him. Shaken by this sudden turn of events, Miyabi waylays Tokura on his morning jog to ask him for advice. Tokura analyzes the situation and concludes that Eri's assertive personality makes her a formidable rival. Miyabi is dismayed to hear that it is only a matter of time before Sakurai and Eri are back together, but Tokura tells her not to give up so easily. He instructs Miyabi to attend as many group dates as possible to gain experience, and she immediately arranges one with the nurses from her clinic. Unfortunately, she has been out of practice for too long, and everything she says on the group date falls flat. Miyabi's confidence is shaken, but Tokura is not done with his lessons.
