@thaonguyenviolet Subbed!
6 Summers looks amazing; very excited to read it.
So long as there are people to feel love, I can't imagine "classic love" going out of style. Trends and conventions may shift, but there will always be a market and an interest in love, even without steamy or graphic scenes.
The Greeks have a half dozen or so definitions for different kinds of love, each with its own merits and audience. It's not that Eros (passionate love) is more inherently valuable than Storge (love of family, like parents to children), it's that potential audiences might drift from one type to another based on their interests. Tapas has practically every kind of love, at least from what I've seen, and people will gravitate to good stories, regardless of spiciness.
I hope that helps. Wishing you and 6 Summers continued success!
