Wdym we don't know? They clearly are together. But, yes, I wouldn't mind some chaoter about them too.
It was like barely 2 chapters, and i don't remember their interaction after those 2 special episodes it would be nice if we get a proper story of them
If they are in the story now, we will probably have their own special side stories too. That's what happened in BJ Alex, I don't see any reason to be different this time, if author doesn't have a certain reason not to do so.
Did everyone forgot that we still don't know what is happening with Heesung and Potato? I love Potato tho
