Rule the Pitch Terminator

To save his sick sister, Evan signs a contract and becomes billionaire tyrant Tristan's personal assist player. Forced cohabitation and Tristan's desperate protection slowly win him over. When a scandal breaks, Evan retires and flees into the rain to protect him — only for Tristan to throw away his trillion-dollar inheritance and follow. Reunited on an underdog team, they win the final against the corporate giants, claiming both the championship and each other.
