There are times where the fan service, honestly, brings the story down. It is over done and the characters are sometimes SO stupid that it's hard to even find it funny, despite that being the intention (I think?) But aside from those (many) moments, the story is quite sweet as it focuses on a mangaka who has his two sisters as his assistants who greatly love and support his dream. While the brother gathers up his harem, most of the girls introduced are unique to each other. Typically I am biased for the sisters and want them to win, but Lemon-san might be my favorite among all the characters.
