The two childhood sweethearts developed a different kind of emotion at some point...
The two families were close friends from elementary school, junior high school, to high school and college. It seemed like he was a biological brother, but for some reason, he didn't want to be her brother anymore.
She is the sister next door. She has been lively and active since she was a child. She likes to talk in front of her brother Mo, who is shorter than her brother every day. But as they grew up, the two became strangers and no longer talked about everything. I don't know since when, the two of them looked at each other unintentionally, which made each other's hearts beat faster, but they buried it deep in their hearts...
