This is my first time giving a review so bear with me. I was hesitating to watch this anime because of the MAL users score about this anime but I give it a try. This anime is not that bad as the other viewers says. The prequel is pretty good.To summarize Nogizaka Haruka no Himitsu: Purezza gives the supporting character a story and little development between the main characters. A kiss on cheek, a hug, holding hands and other fan service. I really enjoy this anime because it's light hearted story. maybe I'm getting tired of unusual stories. this anime is about normal people doing normalthings (sometimes unusual but it's part of an anime). One thing i want to say, Give it a shot. Don't judge an anime if you haven't watch it.
Overall I have fun watching this series.
