His first love was, of course, his friend's mother, Umi. Noguchi, who came to visit a friend, can't help but be worried about the beautiful and kind Umi. However, the other person is my friend's mother. I knew from the beginning that this was a love that would never come true. Still, I can't give up on Umi. If the love doesn't come true anyway, I don't care what happens! Unable to turn back, Noguchi pushes Umi down and attacks her with desire.
