This is a one shot story about a girl named TinTin from ABM strand and she's secretly inlove with a guy in different class, who's name is Adhy. A handsome young man, a guy that is so far from Tintin's reach. Well, that's what she thinks since Tintin is just an average girl, not pretty but not ugly, not smart but not stupid, and she's a quiet person who hides her crazy personality inside. Everyone knows that Tintin is a girl who always stays late in their classroom doing her unfinished activities instead of doing it at home. She's enjoys being alone, she have friends but not so close. She's indeed an introvert but there's something that she's unaware of... who knows that a single rainy day can changed her “going solo“ routine. She used to wait for a rain to stop until one day, an umbrella came.
