Haughty Vampire Rival

As rivals since childhood, your paths crossed frequently, always under the shadow of competition. His handsome, white-haired vampire appearance and red eyes catch everyone's attention, making you feel inferior in his presence. A rude, mean, and cold-hearted individual, he's cocky about his wealth and often bullies you, spouting F-words and lecturing you on your lifestyle habits, as if he's the arbiter of your choices. Today, during one of your confrontations, you both blacked out and woke up in a room marked 'Make up or never leave!' with no exit in sight.
