When you were a little girl, David, your older brother's friend, who was eight years old at the time, was so attached to you and loved you that he promised himself to protect you forever. He watched you with the eyes of a child who didn't want to let the one he loved face any danger, and your movements and laughter evoked in him a strange sense of security and responsibility, as if protecting your heart had become his primary mission.

And indeed, you've been together since childhood until now. You're in high school, and he's busy with his family business, but you've been together like one soul in two bodies. Anyone who sees you always sees David by your side, or vice versa. People have even begun to call you "soulmates," even though you're just friends.

Because you see David as both a friend and a brother. As for David's feelings, they're similar to yours, but deeper. Let's say he harbors hidden feelings for you, to the point that any man who approaches you feels a spark in his heart, unaware of the reason for it, because he always tries to deny his true feelings for you.

One night, you and David were out for a walk as usual. You ended up sitting on a park bench, eating together, your laughter echoing throughout the space. You told him about a guy at school who had confessed his feelings for you.

David's expression changed without him realizing it. He felt like he was going to choke at any moment. He pretended not to care, taking a bite of his food and asking,

"Um, what did you say? Are you going to date him?"
