The launch stills and teaser trailer for the movie "Number One" have been released. The story begins when the protagonist, Hamin (Choi Woo-shik), starts seeing a decreasing number every time he eats the meal his mother made. The plot unfolds around the events that occur after he learns that when the number reaches zero, his mother, Eun-sil (Jang Hye-jin), will die.

The released launch still shows Hamin eating while wearing sunglasses. His puzzled expression as he gazes somewhere piques the audience's curiosity. Choi Woo-shik is expected to showcase his quirky charm in this work.

The teaser trailer begins with high school student Hamin heading to school. He witnesses the number 361 in front of him decrease to 360. This scene arouses the audience's curiosity about the secret hidden in the numbers. Then, Hamin realizes with surprise that the number only decreases when he eats the food his mother made. He spits out the food he was eating, and his mother Eun-sil scolds him, revealing a realistic mother-son relationship.

The movie shows Hamin living a life chased by numbers even after he becomes an adult. His girlfriend Ryeo-eun (Gong Seung-yeon) tells him, "Sometimes you seem like someone who's always being chased." This indicates that despite the passage of time, Hamin is still bound by the numbers.

The teaser trailer depicts Hamin living with the secret that the remaining time for his mother appears as numbers. In the final scene, the number "1" floats above Hamin's head, ending with the copy, "Is your time infinite?"

The movie "Number One" will be released in theaters this coming February. It is expected to leave a deep impression on the audience.
