Definetely JUNAI ROMANTICA
As a lot of fans on many forums demanded it in English (me too)). Moreover, trying to read it with my bad knowledge of Japanese + random translation to Eng of two first chapters, I noticed it's very well-written and draws on an amusing analogy with Junjou Romantica manga. The plot is also quite captivating. The series is also very popular in Asia, as my friends mentioned.
Hope to read it in English sometime!!
