Seme: 30~40 uke:15~17???(￣∇￣")

Not too bad tbh. My uncle has been dating someone for like almost 20 years, but he's 30 or so years older than her. When i first met her and she was in her early 20s i thought she was his daughter, lol what an awkward first time meeting. He's like 72 and shes like 41 or 42 now.

Yeah, in the past it's common to date a lot younger/older partner, and the setting in the manga was just perfect.
