The Balance Game

Miso's so indecisive, she can't even choose her own lunch. But one day, a mysterious screen appears before her, and she's automatically entered into a love triangle between an older co-worker she's had a crush on, and Woosung, a younger man who's been crushing on her. The game leads on the relationships by continuously forcing Miso to make choices, including one that may change her life forever.
