The third episode of the Japanese TV drama Koi wa Deep ni, starring Kento Hayashi and Yui Kishi, aired on April 30, 2025, at 10:00 PM. This drama, produced by the same team behind Anata no Ban Desu and Shin Hanzainin Flag, is described as an "ultimate love mystery" that explores the complexities of love intertwined with suspense.
In this episode, the story continues to follow Hiroki Shitara (played by Kento Hayashi), a freelance writer for a weekly magazine who may be linked to a series of murders, and Mio Tsutsui (played by Yui Kishi), a TV station information program director who finds herself deeply attracted to him. Their relationship intensifies as they investigate the mysterious "Holms no Me Murder Case" together, leading to unexpected developments.
As the plot unfolds, Hiroki and Mio's connection deepens when they spend a night together while covering the murder case. However, when Mio wakes up the next morning, she finds that Hiroki has disappeared. Before she can process his absence, she discovers a small tin case in his apartment that contains a name tag from his elementary school days, raising questions about his past.
Despite their intimate night, Hiroki acts as if nothing occurred when they meet again at the filming location, leaving Mio confused and frustrated. Her feelings of uncertainty grow as she grapples with Hiroki's aloof demeanor.
Adding to the tension, a male junior high school student living near the fourth crime scene claims to have seen a suspicious figure in a black raincoat on the night of April 4, 2025. This revelation could potentially lead to a breakthrough in the case, as the student identifies Hiroki as the man he saw near the scene. Mio, eager to uncover the truth and stop the serial killer, decides to feature this information on her program.
Meanwhile, detectives Seisho (played by Jin Shirasu) and Owada (played by Yuzuki Rina) confront Hiroki about missing data from a car's drive recorder that allegedly captured footage of the "black raincoat man" on the day of the incident. The detectives question whether Hiroki deleted the footage, further complicating the investigation.
As the date of May 5, 2025, approaches—a date that may see the next murder—Mio begins to notice a pattern among the four previous crime scenes. This discovery hints at a possible fifth crime scene, intensifying her resolve to solve the case. Simultaneously, the evolving dynamics between her and Hiroki suggest that their relationship is on the brink of a significant change.
The episode concludes with a promise of more revelations about Hiroki's enigmatic past, leaving viewers eager for the next installment. Koi wa Deep ni airs every Wednesday at 10 PM on the Japanese TV network, captivating audiences with its blend of romance and mystery.
