Happy Sisters

Yoon Ye-eun has been a devoted wife for seven years, keeping the household together and shouldering her in-laws' expectations while staying upbeat. When her husband's business appears to thrive and they move into a new home, she learns he is having an affair, and her life begins to unravel. Her sister, Yoon Sang-eun, runs a small piano academy but is drowning in debt. Sang-eun accepts a contract marriage offer from Choi Jae-woong, who promises to clear her debts in exchange for the arrangement. The intersecting choices of these sisters set off emotional reckonings, shifting loyalties, and tense family confrontations without revealing any final resolutions.

Created by Go Heung Shik and Han Young-mi, Happy Sisters premiered in 2017 and features Ban So Young as Jo Hwa-Young, Shim Yi Young as Yoon Ye-Eun, Jung Geun as Gong Il-Sam, Lee Sung-wook as Hwang Soo-Chan, and Go Na-Hee as Hwang Soo-Ji.

Critical response was mixed and audience scores were modest, leaving the series with a small but engaged viewership. Reviewers and viewers tended to note strong domestic drama elements, with the story centering on marriage, infidelity, financial strain, gender expectations, and the responsibilities siblings carry for one another.

While Happy Sisters never became a mainstream breakout, its straightforward depiction of in-law pressure and contract marriage scenarios resonated with a segment of domestic drama fans. Conversations about specific episodes and character choices appeared on online forums and social feeds, where viewers traded opinions about the sisters' decisions and moral dilemmas.

The series did not secure major industry awards or widely reported nominations, and it remains better known to a niche audience than to award committees. Its ongoing recognition comes mainly from viewers who discuss its family-focused conflicts rather than from formal honors.
