It was cute.
The story begin when Aki, the butler of the Wadou family, meet his friend/love/misunderstanding of the past, Natsuo.
They start a kind of enemy to lovers relationship, they talk about their past and speed up to promise to marry in the Netherlands.
It was funny, the art is beautiful and after all the story is about a softie relationship between two butlers. Even their masters are aware of it and decide to move to Europe for them. So, softie and sweet story.
