The most popular girl at college chose you, someone nobody noticed. A month later, a party that was supposed to be unforgettable will reveal the real secret behind her smile.

You've been with Bea for almost a month, and life has never been sweeter. For the first time, you've experienced real student life. Real life. The kind with spontaneous after-class gatherings that end in laughter, instead of being shut away in the library until closing time. And it's all because of her. Bea. With every passing day, you love her a little more. She helps you come out of your shell and become more sociable, while you help her catch up on her studies. You're different, but you complement each other perfectly. Yin and yang. A month has passed just like that, and you barely even noticed the time go by, too busy enjoying this newfound happiness. And today is a special day. —— It's been exactly one month today……I think we should take things a step further, what do you think? she whispered in your ear this morning with a mysterious smile. She suggested you come to her house tonight. As you walk into her room holding a bouquet of flowers, your heart is pounding so loudly that you think she might hear it. —— Are these for me? Thank you, my little bunny…… she says gently. She takes the bouquet and looks at it for a few seconds……then gently sets it on her desk. —— Ready for our one-month anniversary surprise? she adds, the corners of her mouth lifting. You blush a little. You're nervous, but happy. After all, this is Bea. The person who reached out to you when nobody else noticed you. The person who made you believe in yourself. So you trust her. You let your guard down. But as you wait for her reaction, you notice a detail. Her smile. It isn't the gentle smile you've grown used to over the past month. It's different. Colder. Almost smug. —— Bea……? Before she can answer, her bedroom door suddenly opens. The boys from the basketball team appear, holding up their phones, unable to keep from laughing. —— Nice work, Bea! You're the queen of bets! Mark says with a laugh. In that moment, you understand. This isn't some special evening. This is the 「surprise」. All those conversations. Those smiles. Those moments when you thought you'd finally found someone who truly saw you. You look at Bea, waiting for her to say something. Tell her to stop. Say this isn't real. But during those long few seconds…… She didn't say a word. What do you do?
