I agree with you, it's somehow adorable how awkward and clumsy they work together, even though it's also somewhat painful to read/write. XD (if you allow yourself to feel for them) I do enjoy writing those thongs though and hope the others like reading them. 

On another note, you'd be very amused if you knew what Hazumi used to be like. This would have never worked on her. Zi is almost her polar opposite and it's so fun to have a character built on the ruins of another.
