I guess this manga tries to make this less creepy by saying the guy isn't attracted to his students and that he only likes his wife, but his wife is a kid now. He is attracted to her body. I know that people might say this is just fictional, but still pretty wrong. If it's the age gap you're into, you can find another comic with a higher age.
I thought something had been posted onto here since it was on the popular list, but I'm glad even more people are reading/rereading it. This manga is crazy lol.
