I'm the Ultimate Teammate in a Mysterious Livestream

There are so many awful characters, and this year they’re going live. A mysterious murder game streamed live suddenly appeared on Earth. It delighted in toying with the players’ lives, and its streams took the world by storm. Su Na joined the game not to win, but because her Terrible Teammate System targeted “special individuals.” Its mission: hold them back and make absolutely sure they couldn’t win. Su Na was confident. For the beginner mission, she picked the most useless, ornamental pretty boy she could find. She would sabotage him, steal his kills, snatch his contribution points, and always stay one step ahead. She came up with one irritating scheme after another. She failed! She failed again, and again, and again! The more setbacks Su Na faced, the more determined she became. With the pretty boy in tow, she charged ahead, carrying the team to victory all the way. Su Na: ?? Something feels off. Theme: As long as life goes on, keep striving.
