Spoilers Ahead
Eriko Shimura works in the seafood import division at Nakamaru, Japan’s largest trading company. Despite her professional success and affluent upbringing, she has never formed a lasting female friendship.
Every morning at 6 a.m., Eriko reads The Diary of Hallie B, The World’s Worst Wife, a blog by ShĹŤko Maruo. ShĹŤko is a 30-year-old childless housewife who writes about junk food and domestic laziness.
When Eriko learns that Hallie frequents a local cafe, she arranges a “coincidental” meeting. ShĹŤko is flattered by the attention, and they arrange a late-night meeting at a Denny’s restaurant.
Eriko feels euphoric, believing she has finally found a genuine friend. ShĹŤko, however, remains casually detached. She is preoccupied with her failing marriage and her blog’s growing popularity.
When ShĹŤko travels to her rural hometown to help her ailing father, she leaves her phone behind. Eriko misinterprets the silence as danger and uses blog photos to track down ShĹŤko’s apartment building.
ShĹŤko and her husband Kensuke find Eriko lurking in their lobby early one morning. Terrified, they draw a firm boundary.
ShĹŤko begins avoiding Eriko. To excuse her withdrawal, she lies to her husband and editor, claiming she is receiving sinister stalker messages, a fabrication she invented earlier for sympathy.
Eriko’s desperation escalates. She confronts ShĹŤko at Denny’s, screaming that ShĹŤko is a cowardly dropout hiding behind a mediocre husband. ShĹŤko flees in tears.
Meanwhile, Eriko sleeps with her colleague Sugishita in a desperate bid for connection. He dismisses her as “stress relief.” ShĹŤko begins professionalizing her blog under a superstar blogger’s guidance.
Eriko follows ShĹŤko to an aquarium and catches her kissing a young waiter. She photographs the kiss and blackmails ShĹŤko into becoming her “best friend forever.”
Trapped, ShĹŤko agrees to an overnight onsen trip to Hakone. The trip is suffocating. In the hot spring, Eriko swims breaststroke naked, appalling ShĹŤko. In the hotel room, Eriko realizes ShĹŤko feels nothing for her.
Upon returning to Tokyo, ShĹŤko confesses everything to Kensuke, including the kiss and the blackmail. Devastated, Kensuke asks for time apart.
ShĹŤko flees to her hometown and finds her father has suffered a stroke. She learns he squandered his fortune on alcohol. A blogger friend reports ShĹŤko as a stalker, and ShĹŤko realizes she has become just like Eriko.
Eriko’s corporate life collapses. She neglects her hygiene and work. A temp worker confronts her, exposing her hypocrisy. Eriko’s division manager rejects her advances, calling her hollow.
Eriko walks in the park with her mother and understands her mother shielded her from real-world friction, preventing her from learning adult relationships. She decides to take responsibility and leave her career.
ShĹŤko takes charge of her father’s care. She cleans his house and firmly plans to sell the property. She sends a voicemail to Kensuke, expressing her desire to rebuild their marriage.
At 3:30 a.m., Eriko discovers The Diary of Hallie B has been deleted. She walks to Denny’s, where her childhood friend Keiko is working the night shift.
Keiko tells Eriko that brief, superficial encounters are enough for adult friendships. Eriko permanently deletes ShĹŤko from her phone contacts. As dawn breaks, Eriko sits peacefully, ready for her independent future.

Quotes from Hooked
“The idea of combining karintĹŤ and the trusty melon bun is, of course, totally stupid. Honestly, I burst out laughing when I saw it there in the convenience store.”
“I don’t see any need for you to get married, at all, but if you do end up becoming a stay-at-home wife, let’s laze around together?”
“I think you’re amazing, ShĹŤko. Someone capable of a lot more. You’re not the sort of person who should be lolling around at home, satisfied with such a spectacularly mediocre husband.”
“You speak different languages, you and her. That’s why you’re finding it so difficult to communicate.”
“You don’t know how to connect with people, so you mistook a regular connection for something special. You blew it up and gave it more meaning than it actually had. That’s all it is.”
“I’m not going to do that any more, let other people decide my worth. I know that sounds easy to say.”
“I think it’s when two people separate that the things they’ve learned through their friendship can really blossom.”
