The film Heartman, which will inject hot energy into theaters in the new year of 2026 (director Choi Won-seop, distributed by Lotte Entertainment, produced by Movieluck·Like M Company), is set to release its OST tomorrow (Dec. 31) and has unveiled a rock-and-roll poster that fully captures the rock spirit.

The film Heartman is a comedy about Seungmin (Kwon Sang Woo), a man who has returned, who struggles to keep the first love he meets again, but a secret he can never tell her emerges and leads to events.

The newly revealed rock-and-roll poster captures attention with Seungmin (Kwon Sang Woo) carrying a guitar and Bona (Moon Chae-won) striking a confident pose by his side. Set against a striking red background, they make the rock peace sign, directly conveying Heartman's delightful energy that mixes love, laughter and rock spirit. In particular, the phrase "Why is love coming back now?" wittily reveals Seungmin's complicated feelings as he faces the first love who has returned in an unpredictable situation, piquing curiosity about what bittersweet-comedic stories Heartman will show.

Along with the rock-and-roll poster reveal, Heartman will release its OST tomorrow. The OST includes songs sung by the actors themselves as well as music featured in key scenes. It contains Eve's 'Lover,' which is inserted into the Ambulance stage, the college-era rock band of Seungmin and Wondae; 'Flying from farther than the sun,' sung by Kwon Sang Woo in the ending scene; and various songs inserted into key scenes of Seungmin and Bona such as 'Back To Me' and 'Brand New,' allowing audiences to enjoy the film's laughter, emotion and rock spirit once again through music.

Heartman, which has established itself as a 2026 film to watch by consecutively unveiling the rock-and-roll poster and the OST release, will be available in theaters nationwide on Jan. 14 (Wed).<
