My name is Rika. I am 16 years old. I have brown hair and red eyes. Yes, I was born with red eyes. I know it's strange. Anyway, it's Valentine's Day and there's something in the mailbox. A Valentine's Day gift for me. I open it in my room. It contains a very valuable necklace and a letter from "X." This mysterious boy wrote me a love letter! He wants me to be his girlfriend. I am so happy. I finally have a boyfriend. My attempts to find a boyfriend at school were always unsuccessful, but now I have one. I can't wait to meet him, but how will I recognize him? I will read his letter again. There must be a clue in there.
