This is one of the most famous works of the CLAMP group. [wich's a quality of guarantee]
It's quite interesting and amusing since's a mixture of drama with comedy like they only know how to make it.
As in most of the CLAMP works, There's many androgynous and not very defined characters, as well as situations not very common.
Even so it is a broadly advisable series besides that the artistic work is excellent.
