It's crucial to mention that the author divided the series into "installments," with the first three focusing on Yuriha's quest to form her harem. These early parts are characterized by jealousy, melancholic undertones, and yandere elements, which made them enjoyable as we witnessed Yuriha's reactions to the romantic advances from various characters.
However, after the initial three parts, the pace slows down significantly, transforming the series into a more slice-of-life drama, depicting the girls spending time together. The yuri aspect takes a backseat, with brief glimpses of it occurring when Yuriha is sexually harassed, which unfortunately becomes a recurring theme and uncomfortable to read about, especially considering her past trauma.
A spoiler follows:
As the story progresses, Yuriha's past rape comes into play, intensifying the sexual harassment. Ranko, who is aware of Yuriha's history, even resorts to drugging and raping her, which is an unsettling turn of events. Moreover, it's puzzling how Ranko, knowing about the harassment Yuriha has faced, becomes the most persistent harasser.
Later on, the series shifts from a harem to a love triangle involving Yuriha, Ranko, and Sakihime, with Yuzuriha and Hinoka taking on more supporting roles. Instead of multiple relationships, the narrative narrows down to two subplots: Ranko, Yuriha, and Sakihime, and Yuzuriha and Hinoka.
Another spoiler:
Sakihime also joins the list of harassers, adding Ranko, Hinoka, and Sakihime, while leaving Yuzuriha as the lone "normal" character. Unfortunately, Yuzuriha's potential shines less due to her reduced screen time. Despite her likability, the series disappointingly loses its yuri harem focus.
In conclusion, the series earns a rating of 3 out of 5. It's a decent read up until the fourth part, but subsequent developments make it a more conventional slice-of-life story about girl dynamics.
