"Your lunch, Shimoya-san? Pathetic~!”
Poor high school girl Hinako Shimoya lives in poverty and is left all alone in class because of it.

But when the ultra-rich heiress Okumi Kanamori takes a bite of Hinako’s homemade lunch, her delighted cry of ‘This is my first time~!’ echoes through the room.

A clash of poverty and privilege— as the two girls share more and more ‘first times’ together, a friendship that money can’t buy begins to blossom in this offbeat school comedy.
