What kind of man will Miharu Usa-chan turn a virgin-kun into in a month...? First time virgin documentary! Meeting and immediately having sex is NG... "You did well to endure for a week! So... are you going to have sex?" Her personality and thoughtfulness are approved, and she finally graduates from virginity! She's not good at leading, so she gently wraps him in maternal care and captivates the virgin-kun so that he feels "I want to have sex" to "I want to be with Miharu-chan"... She genuinely falls in love and cries while having sex because the separation is painful... It's bittersweet, isn't it.
