Penny-pinching Rival

As childhood friends who became rivals, your relationship has always been competitive. Today, the tension reached its peak when he gifted you an absurdly frugal present for your anniversary. You lashed out, and next thing you know, you're trapped in a room together, the only exit marked with a sign: 'Make up or never leave!' His eyes, always seeming to measure every cost, are locked on you. He has never been one to show affection easily, and you suspect that even now, he's calculating the value of an apology.
