Shizuku is clearly affected by Haru's presence, but she is doubting if it is what people call love. To further complicate matters, Chizuru has developed romantic feelings toward Haru. In a strange fashion Chizuru has entered Haru's circle of friends. The highlight of this episode to me was when Chizuru questioned Haru's manliness because his nonchalant attitude seems like apathy towards Shizuku. There was some interesting character development on Shizuku's past, and the fact that her mother left her family.
A lot of things happened in episode 6 of My Little Monster. Chizuru has developed romantic feelings toward Haru in a very short time. Shizuku has gone from being jealous and hopelessly in love to deciding that her studies and future are more important than love. The detail of Natsume being upset because Shizuku does not confide things with her was intriguing. I would like to give a 9 to this episode (it gets a 8 out of 10) but the creators are doing a bad job not developing more on all the information being dumped.
At the midpoint (assuming it is 12 episodes long) My Little Monster is a good series, but it is dangerously in risk of becoming mediocre. The premise is still interesting, but the creators need to step it up and focus on fewer story lines. The show has become kind of convoluted in the last few episodes.
