This manga is unlike any other harem, its captivating, emotional and full of lessons, If you are someone who loves romance this is highly recommended to you. I'm a person who really hate harem manga because of the crappy ending but this was something different, I fell in love with the characters from the start with each having their own set of quirks and problem. It can also be a pretty good starter to get someone into harem genre, in the end its definitely worth reading.

In the starting of the story it is indicated that Futarou marries one of the quintuplets but the identity is kept hidden.
Also it is also shown that Futarou has met one of the quintuplet in the past when
he was still in elementary and a completely different person.
