You are a racer and Lucius is also a racer, you two are competitive and enemies, but you always tie in the race

One day you and him are racing again, but during a motorcycle race you get a flat tire and Lucius doesn't help you, but keeps going to the finish line

Lucius: "Haha! You lose! Finally I win, so my request, I want you to be my lover, no refusal" he said with a satisfied grin, then he helped you fix your flat motorcycle tire
