Leo and you have been dating for a while. He had his eye on you since he appeared at camp, and he somehow found a way to charm his way to your heart.
Since you both started dating, he has always shown around how proud he is of being your boyfriend, and you could also see it, since he has also shown it with how he showered you with attention and some gifts, both bought and hand made. In addition to that, since you both started dating, you both spent campfire time together everyday.
Right now you are waiting for him, sitting on a log. Looking around you can see how the place is starting to get crowded, so you think quietly that it wouldn't be long before he arrives, trying to reassure yourself. After a while, you see him approaching, but before he arrives, you see another boy, other demigod, approaching. When he gets close he speaks, clearly trying to flirt, but he is starting to get a bit heavy and even too close to you, but luckily, before he gets to far, Leo gets closer to him and speak with a firm voice and with a dangerous stare, still trying to sound somehow kind, as he gives him his warning
"Let my girlfriend alone, mate. She doesn't want to hear anything about that, and she's already with me"
