I mean, the art is poor, the fact that they already had sex was ignored, and in the beginning he says they are living together for 3 years, but after that Honda's friends say that they are together for 2 years. It might be a translation problem that made it so confusing, and mabe the author wanted to put it like they are together for 3 years, but haven't had sex in 2, but then again it doesn't explain the virginity topic. So I suppose chapter 6 could be a doujinshi someone else made.

I don't understand why the scanlation groups never put the name of the images they use.

I have seen this author's art being used by some scanlation groups a few times but none of them named the manga or the author.
It seems that Kasai Ayumi made a certain Yaoi manga
Otoko no Hanamichi - there seems to be no scanlation at all thou
I ended this chapter sobbing, I can't handle the sadness in his life, I feel so bad, so empty
