On the top layer, the original reason you most likely will try it out, is for the fanservice. The main lure is large-breasted women in varying situations with male audience-inserts. Many fantastical but realistic-feeling situations one wishes they could find themselves in, scattered across a variety of different parings all still centered mostly around the fact they have large breasts. The fanservice I definitely won't complain about, but if it isn't your thing this is 100% not for you.
The other layer of this story is what happens when you get used to, and surpass the fanservice, admiration. Every chapter in this is pairing-specific, focusing on one guy and girl, and while chronological, jumps between the different characters and progressing them at different rates in an episodic manner. Like I said previously, very similar to Tsurezure Children. As I jumped from pairing to pairing, I was delighted to sometimes see and interact with the other pairings as side characters in other's stories. It gives the characters and their stories a lot more validity and creates a feeling of wanting to know more about all of them.
Although the stories are fairly short, aside from some moments, it does a very efficient job at capturing a unique essence that straddles the line of platonic and romantic, that which a lot of people both desire and despise to have.
A good food metaphor for this manga would be an American Mid-western Biscuits and Gravy Bowl. You get it for how much gravy it has, and you might love the gravy, but you might also be surprised and relieved at how delicious the biscuits under all that gravy actually are as well.
