After a "hospitality date" with Sumi, Kazuya finds something he can do for Chizuru.
However, reality is harsh, and Chizuru receives a rejection notice for her movie audition.
Considering the new auditions and filming schedule, her dream of showing Sayuri a movie she's appeared in seems unlikely to come true.
"Don't just laugh, tell me... Grandpa..."
A photograph of her late grandfather's smiling face and Chizuru's feelings from days gone by intertwine...

One morning, Kazuya is summoned to the balcony by Chizuru.
Apparently, Sumi wants him to be her "practice partner" again as a rental girlfriend.
Kazuya agrees, but he's distracted, worried about Sayuri's condition and Chizuru...
When he arrives at the meeting place, Sumi appears looking different than usual!?
"Today, I wanted to 'treat' you, Kazuya-kun..."

The sudden kiss with Ruka made Kazuya realize how much he had been making her endure.
As his thoughts of Ruka raced through his mind, Kazu tried to hand Chizuru a small box.
It was the engagement ring he had received in the past, and he wanted to give it to Chizuru...
Seeing Chizuru's confusion and Ruka's distress, Kazuya made a decision.
"Chizuru can't accept this..."

Every year, Kazuya's birthday party is held at his family home.
Having missed celebrating Chizuru's birthday, Kazuya decides to hold a joint birthday party for
both of them. Kazuya tries his best to get Chizuru to come, but on the day of the party, Ruka suddenly appears before Kazuya and says,
"Now, shall we go to your family home?" ...!?

When Kazuya checks the website to rent Chizuru after a long time, he's delighted to find that she's been promoted. He tries to justify his decision by thinking that she might be bored with their usual predictable dates.
"Hey there,"
says Chizuru, appearing at their meeting place in her school uniform. Kazuya's dream date from high school is about to begin...!

Suffering from a hangover, Kazuya was unsure how much of what happened last night was real.
Later, when he met Ruka at his part-time job, he told her that Chizuru had believed their relationship was a misunderstanding.
Ruka pressed him for an explanation, but their conversation was interrupted by the arrival of a customer.
"Oh, hello, Kazu-kun."
It was Asami...

Having cleared up his misunderstanding with Ruka, Kazuya feels he has grown closer to Chizuru as a fair neighbor.
Then one day, Kibe invites him to a drinking party, asking,
"By the way, Kazuya, can you come to the drinking party tonight?"
When Kazuya arrives at the izakaya, he finds "Ichinose Chizuru" there—…?

The morning after his night with Ruka, Kazuya unexpectedly runs into Chizuru.
Trying to act naturally, he invites Chizuru to rent him a girl, but she refuses, still misunderstanding his relationship with Ruka.
Desperate to clear up the misunderstanding, Kazuya realizes it's Chizuru's birthday and makes a decision.
"I'll celebrate her birthday properly and somehow clear up the misunderstanding!"

As Kazuya is printing documents on the university copier, Mami appears and tells him that she knows Chizuru is a rental girlfriend.
Knowing about Mami and Chizuru's interactions, Kazuya tries to cover it up with an exaggerated reaction.
Seeing Kazuya's panic, Mami says something unexpected...
"You're not serious, are you, Kazu-kun?"

When Kazuya returns home, Chizuru, whom he had just parted ways with, comes to visit him.
"I...lost my keys..."
Kazuya is confused and excited at the situation of having Chizuru in his home.
But then the doorbell rings a second time, and a second visitor enters Kazuya's room.

Determined to continue supporting Chizuru, who is downcast after missing an opportunity, Kazuya immediately tries out the rental girlfriend service.
After their date, as usual, Chizuru says something different to Kazuya.
"Do you have some time? There's somewhere I'd like to stop by."
Off-duty Chizuru, not working as a rental girlfriend, invites Kazuya to a certain place...!?

"Maybe I could make a living solely as an actress,"
Mizuhara Chizuru, who was pretending to be his girlfriend, said, putting the hopeless college student Kinoshita Kazuya in grave danger. Chizuru said that if the play she was appearing in as an actress was a success, she would quit being his rental girlfriend.
Seeing information about the play, Kazuya secretly went to the theater. And then, the curtain rose on the play that would determine his fate...
