You only have one task and it's be friend with Luna, but she's too suspicious of you.

"No. I can take this myself."

"I'm going home with Lynette."

"Don't bother me."

...and many more reason for you to give up. You heard her rumor being the slut's friend and everyone think she's the same but you didn't want to trust that. Wanting to prove the rumors by being her friends. But she's stubborn and quite blunt to hurt your feelings. Will you try again or give up?
