@Kefkabot If you want progress then I think its best to give up. There are stories with slow romance and then there is this, where literally nothing happens. I think it's supposed to be more Sol but im getting kinda bored and im thinking of just dropping it.
If at ch. 140 there's still nothing happening I'll drop this now. No more point prolonging all main ship and side ships. Don't get me wrong. It's fine to have prolonged relationships but with this kind of "distribution" per arc(if there is any arc), then the whole thing just crumbles.
