I hope there is a extra or something, the last chapter was so sweet and good. The sex scene was so well done, it didn't need to be smutty or over the top. It conveyed their feelings really well and put any doubts that I had about their future aside. It was great, I'm really enjoying this mangaka work.
It was really good, and sweet and different. The problem is that I want more from them (✿╹◡╹)
EDIT: THERE IS MORE
But only the doujinshi where translated
Kocchi Muite Waratte - Look At Me (Sequel)
Kocchi Muite Waratte dj - Call, Re:Call, Un:Call. (Sequel)
Kocchi Muite Waratte dj - Look At Me (Sequel)
Kocchi Muite Waratte dj - Switch! (Sequel)
I know that the last panel seems like it's bad, but maybe it isn't. Maybe they were able to sort their stuff out and be somewhat together. I think it's left for interpretation if the reader wants it. Since it's a oneshot, of course that within that limited world it's a sad ending for their relationship, but realistic, even in a fictional world, there is always more after something happened.
To me their bond can be mended if they really want to, there are a lot of challenges of course. The fact that they both build up families and it's implicated that it's a big reason why the boss may not be willing to "go together" with him after all these years (and that's the moral of the story, how one mistake can have a huge impact in your life, changing it completely to something that you may not even want to and how it's hard to undo that mistakes because of how your life is right now. Basically, the story is about consequences), that doesn't mean that its impossible. If this was a series, with more chapters, I think it could be a story where they end together.
This is getting too dark, someone needs to do something about Sigmund. I hope Noah will be alright (╯°Д °)╯╧╧
