Such a shame this got axed so early. It had so much potential. Also the premise of a symbiotic parasite is extremely rare. The only other I can think of was
Parasyte but in there, migi (the parasite) wasn't able to take over the hosts brain. So as of right now, this manga is the only one that covers a symbiotic relationship where the parasite shares the whole body.
So I wonder what the issue here was. The art was decent. The romance part of the story was cute. The premise was interesting. But while other, less interesting romance/slice of life manga usally get at least +40 chapters this one didn't even make it until 20.
The average reader really seems to like gobbling up slop.
