I mean he went missing. I have looked in the lake, market, everywhere in the guild house and pretty much every other place. Of course the side stories and other things are nice.. But i wanna progress the main story too.
Go to that stairs location where Luna stays at night (forgot what the location is called). Just keep going up the stairs and you should get a cutscene. If nothing appears then you probably have to do more tasks or level up the girls more.
