I'm really curious why this is cast as a "Japanese girls are lonely". My girlfriend also watches those horrible Asian romance dramas and (jokes notwithstanding) I'm pretty sure the reason is more to fulfill her sappiness quota and not to cure her deep aching loneliness.

I think its more notable for its interesting game mechanic and the utterly evil method they have for getting high page counts per user. (I mean, it seems that the company just implied you advance in the game by looking at pages you wouldn't have looked at normally. Devious!)
