OK, let's look at some proper yuri from the genre's first and biggest supporter: Seven Seas. They put out a lot of good yuri titles this year, but this one may be the cheeriest of them all.
KASE-SAN AND MORNING GLORIES (Kase-san shirizu...), by Hiromi Takashima. First published in 2010 and first published in North America in 2017.
PLOT:
Yamada and Kase first meet when they discover that they have been both tending a patch of morning glories on the school grounds. From that point on, Yamada is obsessed with Kase but believes herself to be too untalented to be worth of Kase's notice. Will Yamada ever find the courage to tell Kase how she feels? Or at least stop denying her feelings long enough to realize she's in love?
