In today's world, having sex just because someone is cute isn't enough anymore. It's frustrating how most young women seem to be selfish when it comes to sex, not caring about their partner's needs or desires. If men had more time, they should focus on improving themselves sexually! Or maybe take a page out of Kohaku-chan's book and learn to become a skilled M-girl like her by attending Hapuba classes alone. Kohaku might look plain at first glance, but she knows exactly what she's doing behind closed doors – giving men the ride of their lives through rough sex and creampies.

もう、ただ可愛いだけでSEXも微妙な女とやるのはつまらない。なぜ世の中の若い女のほとんどが自分のためだけのSEXしかしないのか。男性のせいにして、バカにする暇があったら自分の性の実力を磨け！もしくはこはくちゃんのように一人でハプバーに通っては犯●れM娘としての感性を磨くべきだ。実は全ての女性の教科書になりうる隠れ地味顔ヤリマン娘こはくは生ハメ中出しでハメ倒すのに限る。
