Summary
After a while, Koichi has changed clothes and Yukako cleaned his old ones as he wetted himself. Koichi express his shame and at the same time, tries to persuade Yukako that he doesn't deserve her love and she ought to let him go. However Yukako is still deaf to his pleas and tells him that she still believes in him; in fact she feels that Koichi is hiding a last side of himself, unwittingly referring to the latter's Stand: Echoes. She then reveals an electric chair in the next room she is building for dinner, and talks about cooking italian tonight, leaving Koichi to go buy olive oil.

This is the last straw for Koichi, who begins to search for a way to escape. As he doesn't know the range of Love Deluxe, he opts to try to contact Josuke, only to find all the telephonic lines cut off. But Koichi remembers that Yukako mentioned buying olive oil, and suspects that she will try to order it with a phone booth, as she should be unwilling to let Koichi alone for long. Sending Echoes up in the air, he sees a phone booth which is fortunately barely in range for his Echoes. However another problem arises as Echoes reach the booth: he cannot pay for the call. Having been kidnapped, and knowing calling the police is useless, Koichi finds himself stuck. Suddenly Yukako appears at the window, startling Koichi who hides Echoes in fear. She easily deduces Koichi's intentions but also that he has no way of calling anyone of help. Nonetheless, she decides to destroy the urgency buttoon after her call just to be sure.

Yukako goes to the phone booth, but as she puts the coins into it, she notices markings on her arm. It is Echoes who has planted dial tones on her without her noticing, and activating them, the phone calls the Higashikata residence, and Josuke picks up his phone. Before Yukako can hang up, Josuke still deduces that Koichi has found a way to contact him and notices the sound of the waves in the background. Yukako is furious as she realizes Koichi too has a Stand. Koichi now has to survive until Josuke arrives.
