Commitment

During a fight scene, actor Seung-hyun Choi (Ri Myung-hyoon) cut his hand from a glass window and was admitted to the hospital for surgery.

When Kang Dae-ho arrives at his new home (at around 11 mins) he looks at the motorbike which is a Ducati. Later on when he leaves the house with it (at around 21 mins) the sound of the motorbike engine is of an inline-4 motorbike. The Ducati (Monster) he is riding should have a totally different sound of a 90-degree v-twin, a well known Ducati low rumble, not the buzzing inline-4 sound we hear.
