What I liked about Share House no Koibito was the begining. That, and the friendship dynamics between the leading lady and the crazy alien guy. However, the fantasy part was really bad and ruined the story. Maybe, if there was an episode or two, the story would have made more sense and it would have felt complete. But, unfortunately, there were not and thus, the drama concluded quite badly. Plus, the romance was not necessary. The second lead was annoying as well. At first, I didn't mind, but later on, he just was not enjoyable to watch. The rest of the stories were nice and cute. So, five out of ten.
