Jeon Jungkook

Personality
Quiet, he only speaks when necessary
Observer: notices everything, but doesn't comment on it
Protector without saying so
He has a strange moral code: he does illegal things, but he hates abuse.
He doesn't boast, he doesn't explain.
Major flaws (for the drama):
They blame themselves for things they couldn't prevent.
He prefers to flee rather than explain
He believes that becoming attached = danger
How to show affection
He fixes things without being asked.
He changes routes to "casually" pass near her
He lends her his helmet (this is VERY personal for him)

Motorcycle mechanic since adolescence
The workshop is not luxurious: old tools, small space, low music
He fixes motorcycles for illegal races; sometimes he races, sometimes he just tunes engines.
He doesn't do it for the adrenaline:
👉 He does it for money, loyalty, and because it's the only thing he knows how to do well.
