After being told to not interact, interfere with her anymore, Kazuya receives a phone call from his Grandmother that told him she would come to his place tonight. What will Kazuya do?

On the way home, Kazuya's ex-girlfriend, Mami tells him that she lied when she said she already got a boyfriend, Kazuya is determined to take this chance to get back together. A few days later, Kazuya goes to the beach with his buddies and decides to take this overnight trip to see how Mami feels about him.

When Chizuru wakes up, she finds herself strayed on a small island near the beach. She remembers that Kazuya saved her from drowning in the sea as she found him lying on the ground near her. As he didn't wake up when she called him out, Chizuru puts her face close to Kazuya's... Meanwhile, to celebrate Nagomi's recovery, Kinoshita family is planning a trip to the hot spring resort.

Kazuya and Chizuru spend the night in the same room at a hot spring resort. Kazuya can't stop his excitement, as he wonders what Chizuru actually thinks of him. A few days later, Kazuya's friend, Kuribayashi tells him that he has a girlfriend, and decided to go on a double date with him and Chizuru. On the day of the date, Kuribayashi introduces Ruka Sarashina.

Kazuya, who follows Ruka to keep her quiet for their secret, is ambushed by her instead. As Kazuya persuades her, Ruka reveals her own secret. The day changes as Ruka called Kazuya at the University while he waits for Kuribayashi.

Kazuya, who has started a trial girlfriend relationship with Ruka, lives in constant fear that his secret with Chizuru might be revealed at any moment. On Christmas day, on his way home from the bank, Kazuya sees Chizuru looking more elegant than usual. Kazuya has begun to think about the cruel possibility of Mizuhara Chizuru having a boyfriend.

After that, Kazuya agrees to go on a date with Ruka and decides to go along wherever she wants to go. However, he was brought to a hotel room.

While Kazuya wonders about what to do with his first paycheck, as he heard from Kibe that Kuribayashi had been acting strangely and mumbling about his distrust of women, he decides to call Kuribayashi. The next day, at the meeting place where Kuribayashi should meet Kazuya, the one who shows up is Chizuru.

Kazuya is asked by Chizuru to help her junior, fellow Rental Girlfriend, Sakurasawa Sumi. When Kazuya arrives at the meeting place, he finds a girl hiding behind a pillar, blushing and shaking. A practice date with Sumi, a beautiful girl who is so shy to talk and can't smile is about to begin!

The one who booked Chizuru was Mami! She had found out that Chizuru is a Rental Girlfriend. As Mami and Chizuru enter the Karaoke room, Kazuya, who is working there, happens to see and wonders what happens between them. In the midst of all that, Mami asks Chizuru if she ever falls in love with someone as a Rental Girlfriend.
