I can't say that it will be a sequel, but most manhwa tend to have several extras at the end. And they tend to be of different couples, so I am sure we will get to read a bit more. Also don't think I have read any manhwas where a couple that was mentioned in one series get there own, they tend to just show up in the extras.
Yeah,, spin offs and sequels are a Manga thing for the most part I believe.
well we got "love is an illusion" (even if it's AU) and they usually create season 2 for the second couple like roommates and dolphin fairy among others.
It's in the latest yaoi update now, got reuploaded so it seems. And as I understand we will be getting a sequel? I'm excited for it. Hopefully it will be in it's own title, not a series of extras.
