"If you become class president, I'll throw you a birthday party." 10-year-old Jimin always has to share. From hand-me-down clothes to the rice straight out of her bowl, nothing feels like it’s truly hers. Invisible between her honor-student older sister and her adorable little brother, she is suddenly presented with a special offer from her mom — if she becomes class president, she can have her very own birthday party. Maybe, just maybe, this could be her chance to finally have a moment that's all her own.
