Which role is more lovable in the Korean crime action movie "Special Delivery"?

Personally, I like the heroine Zhang Yinhe played by actress Su-dam Park.

Zhang Yinhe is a courier and driver with superb driving skills. The express delivery business she handles is responsible for transporting items that cannot be mailed by post offices and express delivery companies. However, she met an accident in a transportation, which involved her in a criminal storm. Difficult goods and 30 billion won of unknown origin make her a target of black and white pursuit. Zhang Yin solved many opponents along the way, and finally she sank into the river with the black police. I believe she survived in the end, but the director gave an open ending.
