I’m going to see Ena, a yang gal in a class rumored to be experienced in slashing 100 people, the exact opposite of me as a yin boy, studying! She is the complete opposite of a “yin” guy. When the test is over, the relationship will end… it should have been, but she promised to do something naughty for me as a “thank you”! Contrary to the rumors, however, she is actually an inexperienced and single-minded girl… This is a pure love story of youth sent to you in a fresh and exciting sex scene.
