"Strict father" and "my brother's wife Ryoko"... The three of us started living together after my brother was hospitalized due to a motorcycle accident, and I saw an unbelievable sight. I had always felt something was off about the unnatural closeness of the two of them when eating and watching TV, but what happened last night confirmed it. My respect for my father's back, which I had been looking at all this time, changed to hatred... and as my admiration for the beautiful Ryoko grew stronger, it turned to jealousy...
