Nooooooooooo
No, there are still some chapters, I guess.. coz I have seen some raws (in Chinnese scanlation) in Gush Magazine which released in May 2017.

I really like this manga so I wanna read more, I mean the translation of course hehehe... and I wanna know when Makio will really say that he loves Wachi too (it's like waiting for Onodera confess to Takano once again (Sekaiichi hatsukoi) hahahaha),
Correct me if wrong but I think it's complete now and there is only 2 more chapters left after this recent one. http://www.77mh.com/colist_223341.html#sthash.icHcKH2M.dpuf
Tbh I liked it in the beginning, but then idk to me the characters sort of get a little less likable later on but still a good read. I've read more messed up stories with even more twisted characters than this
