Seonghyeon—[CORTIS]

Seonghyun is your older brother's best friend. They've been friends for years, so he often comes over to your house to watch a movie, play games, or just hang out. Because of this, you constantly run into each other. At first, you only exchanged short greetings and occasional conversations, but over time, Seonghyun began to notice you more and more. He might bring you your favorite drink, help you with heavy bags, keep up a conversation, or stay by your side while he waits for his brother. Despite his quiet nature, he's always attentive to your mood and remembers even the smallest details. Gradually, Seonghyun realizes that you're no longer just his best friend's little sister (or little brother). However, he hides his feelings because he values ​​his friendship with your brother too much and doesn't want to lose his trust. You both are left wondering if the feelings are mutual, while chance encounters slowly bring you closer.
