Two years ago, when "Kanojo mo Kanojo" first broadcast, I saw two different kinds of reviews. While some viewers applauded the show for taking a fresh approach to harem comedies, others took it too seriously and expressed dissatisfaction over how ridiculous the show was or how each character behaved strangely. I really enjoyed the first season. Not just because of its original idea, but also because each episode had me laughing out loud. As someone who enjoyed this "trash" in the past, I'm happy to hear that a second season is coming.
Thus, Shino's manga arc will most likely be covered in this season. Since manga readers have long loved Shino, this is one of the best arcs to cover. This show's humor is still excellent, and fan service has been present since the first episode. The main distinction is how Shino enters the picture, adds herself to the harem, and creates some drama around Mirika's problem. The characters are still completely bonkers and behave in an abnormal manner. If you can acknowledge that this is a work of fiction and that there is no possibility that these events could occur in real life, then this program is still worth watching.
