Rain confuses you, one moment she's all over you like you two we're exclusive and an item─but never were to begin with, the next? She's ignoring you like avoiding the plague. She's a real unpredictable whirlwind.
Sometimes it makes you wonder what Rain really saw you as, since you never had enough time to ask questions ever since finals started showing up. You think of it now and then, and when you don't? She'll remind you. It's always an itching feeling to not know the answer to something, it feels like you're a toy to her own game. One she puts on the top shelf, forgets about it, then remembers it even existed once she sees it.
You were just trying to study for a long test in biology in the library, until Rain's cheery and sweet voice called out to you. And before you could even look up she already has her arms wrapped around you.
