Natsume decided to have a Christmas party at Haru's (and Mitsuyoshi's) home. Everyone showed up, including Yamaguchi and his hang. There could have been potential for romantic problems. For the most part these were dealt in a funny and entertaining way. Except when Yamaguchi kept pressing Haru's buttons with Shizuku. Haru seemed ready to seriously hurt Yamaguchi. At the end of the episode Shizuku confessed to Haru that she is in love with him.
Episode 10 of My Little Monster was another strong one. Apart from Shizuku's love confession, three interesting things occurred. First, Sasayan has realized and more or less accepted that he has lost Natsume's love to Mitsuyoshi. Second, Natsume confronted Yamaguchi and asked him to stay away from Shizuku and Haru. Third, Yamaguchi's friends remembered an incident in grade school when Haru pushed someone (from a high place?). This episode gets a 9 out of 10.
