Magalumina

April, spring. A quiet port town in the countryside.

The protagonist, Fukutome Yamato, came to Japan to begin living on his own. He was a seemingly ordinary young man, apart from being half-Japanese –

"I get lost." "I'm mistaken for someone else." "Even the packages delivered to me are for someone else." "My life is, in short, plagued by 'mistakes'."

No sooner had he arrived in town than a princess from some country fell from the sky. Due to a double contract for an apartment, he ends up cohabiting with a female spy. He's made to attend a different school than planned, and catches the attention of a suspicious, low-level gal classmate.

"I want to live quietly without drawing attention."

He grumbles, but he's also excited about this bustling, deception-filled new life.

This is a cheerful tale of "deceptive love" spun from lies and mistakes.
