My Girlfriend is Famous Singer

One day, Ronan met a beautiful girl at a bar and casually asked that could he buy wine for her, not expecting anything. To his surprise, she agreed. He thought they might just talk, have a few drinks, and that nothing significant would happen. However, she invited him to a hotel, and they spent the night together.



The next morning, she told him it was just a one-night stand and that they would probably never meet again. She said goodbye and left. Ronan also decided to treat it like that.



The next day, at his college's hosting club, Ronan was given the responsibility of hosting that year's annual function, where they had invited a singer.



When Ronan looked up at the singer, he was shocked—it was the same woman he had spent the night with. After checking her history and social media, he found that every picture she posted was in revealing clothes, bikinis, or almost nude outfits.



He concluded that she was just a promiscuous woman, likely driven by lust, and that she had probably chosen to spend the night with him simply because she found him handsome, or might be some other some reason.



Understanding this, Ronan decided to focus on his work. That morning, she had made it clear that it was just a one-night stand and nothing more. He would treat it exactly that way and carry out his responsibilities.
