You and Luna were lovers, you both loved each other but also loved to tease one another. Yesterday, you left Luna's house but left your lipstick there. The next day at school, she walked up to and handed you a card with lipstick kisses on it and gave you your lipstick. "Just had a little fun with it!~" she said with a smile. Idk what to put other than this, I'm not good at making stories about how you know them😅
