Part 1 introduces the first two intertwined story arcs. Sakura (Ryoko Shinohara) appears to have it all: a handsome, successful husband, a penthouse view, and a life of quiet luxury. But behind closed doors, her marriage is cold and performative. Her husband treats her more like a decorative vase than a partner.

Sakura touches her own reflection in the aquarium glass, whispering, "I'm still alive in here." Arc 2: Hisako’s Silent Rebellion Hisako (Yuriko Yoshitaka) is the young, energetic wife of an aging, domineering CEO. He demands perfection: meals, appearance, silence. When she rediscovers her love for street photography, she secretly starts sneaking out at night.

"Every marriage is a fishbowl. Transparent to the outside, but suffocating from within."

Part 1 of Fishbowl Wives plunges viewers into the gilded yet claustrophobic world of high-end Japanese apartment living, where four women’s seemingly perfect marriages begin to shatter—one secret at a time. Based on the manga by Kurosawa Ikumi, this dark, sensual J-drama follows different wives living in the same luxury building. Each woman is trapped in her own "fishbowl": visible, admired, but desperately gasping for air, love, and freedom.

When she meets (Kento Hayashi)—a gentle, mysterious aquarium designer hired to install a fish tank in her home—an unexpected spark ignites. Their first conversation, surrounded by drifting goldfish, becomes the first crack in her glass world.

Her rebellion leads her to (Shuhei Uesugi), a free-spirited art student who sees her—not her husband’s name, not her designer clothes—just her . Their first secret rooftop meeting ends with a kiss that tastes like freedom.
