An borderline h manga with slow romance and a lot of interesting characters.

The main character gets dumped by high girlfriend and after his time in the company of the three sisters he falls in love with the middle sister. He decides to stay and work at the company.

Throughout the course of the manga we are shown the cute romance between the MC and the middle sister develop from a crush to actually love and eventually into a healthy sexual relationship. We see the youngest sister grow up and the older sister doesn't change all too much but is a enjoyable character.

Art is basic but not too dull to the eye. It's not clean enough for me to hate, so it's a win in the art department.
