Seo Hyun-jin, known for her transformative performances in Another Miss Oh and The Beauty Inside, will play In-ji, an employee of an intriguing matchmaking organisation called NM. Gong Yoo, celebrated for his roles in Guardian: The Lonely and Great God as well as Netflix's Squid Game and The Silent Sea, is taking on the role of Jeong-won, a solitary music producer who finds himself in an unexpected marriage contract with In-ji. 

Jeong-won ironically meets his ‘second wife’ In-ji through a contract-based marriage service arranged by his ex-wife Seo-yeon. However, they find themselves thrown into a whirlwind of secrets and events involving the matchmaking service when a mysterious trunk is found in a lake. 

Penned by Park Eun-young of Hwarang: The Poet Warrior Youth and directed by Kim Gyu-tae of Our Blues, The Trunk is set to attract attention for its unique storyline and the dream pairing of Seo Hyun-jin and Gong Yoo. The Trunk will premiere exclusively on Netflix.
