First of all, I cannot emphasize how fucking cute these characters are in this series, it's like they want you to melt on the floor and then evaporate, rain down and start the cycle all over again.

Okay so, story ; no spoiling, so it might be vague but, it's about how these new college freshmen and their respected faculties have cherry picked the most perfect, and representable students from their group to compete in the battle of moons.
( both girls and boys compete for their own title).

So development of characters and how it plays along with the main idea which is winning the battle of the moons.

~ pha is a dream Boat. clearly all you need to know is that he at first is a stuck up, typical handsome and fandom able person whom everyone loves and he's pretty smooth with those who he keeps a relationship with, some of his qualities change over time ;).
~ Yo. O . M. G. The definition of Kawaii literally. The sweetest, kinda awkward, but brave and he sticks up for himself and what he believes in, sometimes swayed by love.. Ooooh getting emotional writing this.
~ everyone else, basically supporting characters are either cute or annoying like phas friends and or his gf. But some of them I loved seeing on screen and playing roles in the greater scheme of things

Overall : my heart my eyes and soul were blessed period .
