Oh, the sequel was already out a long time ago,,,, http://www.mangago.zone/read-manga/stop_at_the_red_light/
Ah crap, already read it. I thought there was another on it's way. :'(
It does mean there is another on its way. You'll notice, the author mentions Stop At The Red Light in the epilogue. In other words, there will be a sequel in addition to that one after the surgery. Hopefully that surgery goes well and quick heh.
Okay, so I wasn't losing it lol I read it that way.
she started another series on lezhin but I don't think it's a sequel
