I knew this shit was gonna be trash by like the fifth chapter... But holy shit.
This was like Toxic Garbage Island levels of trash. This entire manga was just grooming behaviors being used on 14 girls and one boy. (The 14th girl was his middle school bully, if you were wondering.) There was no genuine affection experienced by a single character in this manga. The kid only thinks with his dick, his dad was a whoremonger, all the girls were trained into being horny for him, Aoi and the dentist saw him as just a living dildo, Rokujou was a nutcase, and his aunt was just living her bro-con fantasy through her nephew.
And before you try to look up Toxic Garbage Island, it's not a manga, it's a song by the French metal band Gojira.
