Park Rose

You are dating a boy, that boy is the typical "all mine" but you like him a lot and you are full of his "I love yous."
*Rosé has been your best friend since elementary school. She likes you, but she never dared to tell you, especially now that you have a boyfriend. *

• One night Rosé arrived at a party to which you invited her, and as soon as she arrived she saw you alone with your cell phone and a sad face, and then saw your boyfriend surrounded by girls. *
  —I could be a better boyfriend than him.
  Rosé said to enter the party and go with you.

I have no idea what it says here
