Feeling almost at her wit's end, she finds comfort in the company of "Yukari-kun," Hayama Yukari (Takao Hayato), the only person who listens seriously to her lessons. Secretly attracted to him, the cute, puppy-like young man, Meiko assures her friend, announcer Maki (Hamagishi Hiyori), that he's just a student. One day, Meiko spots Yukari-kun being harassed by some delinquents in town. Just as the delinquents' clutches reach out, Yukari-kun takes a surprising action, shocking her. Then, upon learning Yukari-kun's surprising true identity, Meiko is left completely confused. The contrast is unfair!

Meiko (Watanabe Miho) is shocked to discover that "Yukari-kun" (Takao Hayato), whom she thought was a cute student younger than her, is actually four years older than her and a detective named "Yukari-san." At the end of class, Yukari-kun is waiting for her at the entrance! Meanwhile, her best friend, popular announcer Maki (Hamagishi Hiyori), is embroiled in a scandal involving a passionate love affair with a national idol! The topic is all the rage among the students at the announcer school. One day, despite knowing Maki's pain, Meiko, driven by her inferiority complex and jealousy for not being able to become an announcer, accidentally blurts out the worst thing she could say. After chasing after Maki, who leaves in a heartbroken state, she loses sight of him, and as she is left feeling depressed, someone appears before her...

Meiko is drawn to her younger student Yukari, only to discover he is actually a handsome police officer older than her. As her best friend becomes entangled in a scandal, Meiko takes on part-time work to help but collapses from exhaustion. When she wakes up, she finds Yukari by her side—leading to a shocking and unexpected situation.

Meiko (Watanabe Miho) and Yukari (Takao Hayato) finally go to a comedy live show together after discovering she already has tickets. Seeing Yukari arrive with a mature look and confidently escort her, Meiko feels her heart race as the outing begins to feel like a real date. However, when an unexpected incident throws the venue into panic, Meiko quickly takes action—only for the chaos to trigger a painful memory from Yukari’s past.

Meiko (Watanabe Miho) is shaken when Yukari (Takao Hayato) receives a phone call from a woman named Saki.

When Yukari later joins them with his junior colleague Shiba (Beppu Yuuri), a drunken Meiko finally makes a bold confession—leaving Yukari conflicted about how to respond.

Heartbroken after a misunderstanding with Yukari, Meiko grows increasingly distressed as both Yukari and Karin stop attending class. When she stumbles upon Karin being drawn into a fraud scheme, Meiko risks herself to intervene and is saved by unexpected help. Afterward, learning about Yukari’s past trauma, Meiko realizes she never truly understood him.
