This is someone's perfect comfort read. But not quite mine. 

Very simple, straightforward writing style and plot. Modern world integrated with dragons, new cafe owner from the lower/middle class, gardener-landscaper from the upper class, training a baby dragon together, past griefs, mutual respect and support. Tensions were low and very easily resolved. Classism wasn't really explored. 

Could be super cozy for the right reader but it was too much repetitive telling instead of showing to pull off the cozy vibes for me.
