Sae is excited about their first trip to Okinawa, now that their feelings for each other have finally been reciprocated. However, Akihito is extremely busy, and they are unable to meet often. The more she longs for them to meet, the more their schedules diverge, causing them to miss each other. The anxiety that Sae thought she had finally found common ground with begins to spread again...

Akihito once again forcibly separates Sae from the man who was making advances on her. To escape the sudden, heavy rain, Akihito invites Sae to his home for the first time. In the room, where only the sound of the quiet rain can be heard, the true feelings that they had stubbornly kept hidden from each other finally spill out...

Since their fight at the hotel, Akihito has been completely rejected by Sae. He tries to reconnect with her, even enlisting the help of a friend, but she runs away from him. "Akihito, you actually want to make up with other people?"—that one comment from his friend makes Akihito realize his own feelings for the first time.

As usual, the two headed to a hotel after an invitation from the university. When Sae returned after taking a shower, she found Akihito in the middle of a phone call with another girl. Seeing how rudely he treated the person on the other end of the phone and his dishonest behavior, Sae revealed her anger.

At Sae's favorite bar, the two enjoy a pleasant time together with the bartender. Just when it seems their emotional distance is slowly shrinking, Akihito blurts out, "Right now, I only have friends with benefits." At that moment, Sae realizes that she had, deep down, been hoping for something more from him.

The two spent another night together at the hotel. The next morning, Akihito remembered he had movie tickets and invited Sae to see them. He knew it was a horror movie, which Sae disliked, but the moment he saw Sae's endearing attempt to care for him despite her awkwardness, Akihito could no longer control his impulses.

Sae reluctantly attends a drinking party after being invited by a friend from university. However, she can't stand the large group and leaves midway through the second round. The image of Akihito surrounded by girls having a good time is burned into her mind, and she is gripped by a jealousy with nowhere to direct it, thinking, "He's probably going to be with one of them after this..."

Sae has slept with Akihito. Confused and conflicted by the intense pleasure she has never experienced before, she faces Akihito at university, but unable to be honest with him, she tries to hide her confusion and embarrassment...

Akihito rescues Sae from the man. They end up going to a hotel together, but there he finds Sae completely vulnerable, a stark contrast to her usual cool demeanor. Faced with her provocative attitude, Akihito's self-control begins to crumble.

Akihito, a college student with a penchant for pretty girls and a penchant for womanizing, can't stand Sae, a beautiful girl who always maintains a composed demeanor. His frustration reaches its peak when he learns that even the girl he was targeting at a group date is infatuated with Sae. Then, one night, Akihito stumbles upon Sae arguing with a man in the hotel district...!?
