its marketed as yuri (same anime production company as kimishinu), the author writes explicit yuri situations in the bonus materials, the author is friends with the kimishinu mangaka and they collabed at a marketing event one time, there are zero non-family male characters (i think there was a male teacher in a panel one time but thats like it), and so far there have been a few small moments of intimacy (a kiss/bite, listening to heartbeats, etc.). i guess its up to you to decide what "real yuri" is for yourself, but the answer is obvious to me and many others.
