If you remember the twins from ep 2 and were curious about what their role is in this series, then you'd be thrilled to watch this ep. It's significant in establishing their characters and future roles. Aside from the fact that they're cute, they're pretty clever and competent for their age. Their backstory is heartbreaking, though, and you may want to prepare some tissues for that if you easily cry over stuff (I cried the first time, too!) Anyway, Takuto was such a 'for gender equality' type, even if he said it out of turn XD
