プロミス・シンデレラ E10: Hayame goes to find Issei, who has not come home, and receives a photo on her phone showing Issei being held captive. The sender was Kikuno. If Hayame wants to save Issei, she must start a relationship with Seigo. Seigo hears about this from Hayame, and notices a hint from Kikuno’s words and comes up with a way to find where Issei is held captive. To pull this off, he will need Kurose and the other employees’ help. Meanwhile, Issei questions Kikuno, asking her why she is so fixated on Hayame. Before long, Seigo determines where Issei is. Hayame rushes out of the inn and heads to where Issei is.
