When I returned to my hometown, I contacted my ex-girlfriend, whom I hadn't seen for four years since we broke up. Her name is Tsukasa Aoi. She is a well-known popular AV actress. She wanted to confirm her love before getting married. Tsukasa is actively blaming me, as if taking advantage of my naivety as I refrain from proposing to my girlfriend tomorrow.

His sexual habits and moral sense are destroyed by the last-minute sexual intercourse that does not end even in the morning...
