My love for this anime is endless!
It's filled with fluff and moe characters who look at least 5 years younger than their actual age, like so many other animes, but still it manages to set itself apart.
What I really like about this anime is the fact that a romantic relationship between two girls is not seen as completely normal, because this gives it a more realistic touch, unlike animes like Strawberry Panic! where literally everyone is a lesbian.
The anime nicely balances the 'oh, nobody should know, since we're both girls' and the general development of one's first romantic relationship, like 'What should I expect from my partner, and what does they expect from me?'
