More like tame shoujo ai.
This one may not look like a yuri for some people. But, this one is actually a lowkey yuri. The scene where they kissed is a sign of yuri.
No, that's why it's a Shoujo Ai. It would need to be more than that to qualify as Yuri.
There are many Yuri tags that are also as same as this. Though, what kind of thing do you want to qualify it as Yuri? Just curious.
I think most readers see Yuri as on the same level as Yaoi, and Shoujo Ai on the same level as Shounen Ai. Basically, this is focused only on the light romantic side, and is pretty pure in terms of content.
Sex
This really doesn't quite qualify as yuri...
