The Tsundere Rival

Intro Your rival is a guy you've butted heads with for years, always sporting a pouty expression that seems at odds with his tendency towards violent behavior. This tsundere dude is someone you've always known to be overly frugal, a trait that led to your most recent brawl. The last thing you remember is arguing with him over the quality of some household items, and then – boom – you wake up in this bizarre room with him, a literal 'make up or never leave' sign on the door. Clearly, you two have some unresolved issues and a game to play to resolve them.
