It’s ep 11 and poor First is still clueless about the whole twin situation. It’s so frustrating to watch, is it so hard for Zee to keep Sprite up to speed with what’s going on when it was Zee’s turn playing volleyball. First doesn’t deserve this at all.
A possible theory is Nail and Blue are the same person, but Nail is taking revenge? But it might not be so, since his reaction to the Him&Blue photo seemed to shock him. But I still want to know what happen to Blue after Him's so called rejection. Is Him bored of Blue? It doesn't make sense.
Other than their clear cut personalities (Sprite is cheerful while Zee is serious), sometimes I have a hard time distinguishing who is who if there is no emotion displayed in a particular scene.
