Hoshokukei Heroine ni Ato 1-nen Inai ni Taberaremasu

I like this manga because it puts a very original and unique spin on the typical romance manga. Although don't get me wrong either as a basic romance manga this one is definitely cute and enjoyable, having the twist of moon people creates the conflict needed to both keep me interested and drive the story.
It is definitely a shake up when the girl you like turns out to be an alien moon person who as tradition eats their spouse. The main girl is a moon princess who eats their love while the main boy is a boy who loves her but doesn't want to die. This dynamic shakes up the traditional romance in a way I have not seen before and opens the door to character development. This is where I feel many manga fall flat where the characters are static, unchanging. But in this manga the characters learn about each others love and adapt that love to each others wants and needs, mainly the want to not be eaten. This is handled brilliantly and the characters are really cute.
I have enjoyed it a good amount and I think you will as well.
