This story brings together traditional martial arts and modern conflict.
Tai Chi is the central martial art, combined with the modern black-market organ trade to create conflict. The protagonist is a Tai Chi heir who conceals his identity, using the ordinary job of delivering food at night as a disguise.
A delivery job on a stormy night naturally leads to conflict. The fight scenes should highlight Tai Chi's ability to overcome force with softness, redirecting an opponent's strength against them. The essence of the martial art is shown through this skill, not through bloody violence.
