Akira an Ω from Tokyo moves to an island where his relatives live with his 3-year-old son, Mamoru. He has more pheromones than other Omegas, therefore in the city there was always trouble.

For some reason, now that I’m a single parent, I’ve decided to put my child first without thinking about marriage, and I was thinking of raising my child in peace on the island, but from the first day I was picked up by Shiro, a fisherman who is famous for being a playboy on the island!? This guy!? You must avoid it at all costs...! Despite my thoughts, I was unlucky enough to get into heat in front of Shiro!?
