Mars

Both FLs are somewhat isolated from the world, and the MLs are thought of as violent bad boys, but have good hearts. Both MLs feel responsible for someone's death, and unworthy of the FL. Both drama and movie have a similar feel.

Motorcycles are the main passion in both male characters. Both of them deal with the death of somebody very close to them.

Based on the manga "Speed Master" by Kishi Torajirou.
Akahoshi is a drifter with great car knowledge who travels from town to town aimlessly until he starts working at Sakurai Motors. The motor competition in town is tough though, and a battle between the top motor shop in town and Sakurai Motors soon ensues...
