The stubborn female protagonist with heart disease vs the high-spirited male protagonist
The words "I'll take you home" made her heart tremble, and just like that, the 18-year-old boy broke into her heart.
He is an older brother, but he is not just an older brother (not a stepbrother or stepsister)
"Don't cry, little butterfly, I love you. Love can span mountains and seas, as well as time and space."
Intention: It doesn't matter, I will love you
