It's a manga that makes me laugh a lot when I remember it because of so many situations and knowing that there were so many people who tried to translate it, but seeing how the love story was very slow, to say the least, and in many episodes it was one step forward and two steps back, they decided to give up on translating it, haha. I thought it was a very good, simple drawing and a harem story with quite special characters. The mangaka has another work that is almost the same, except that it is about a rich high school girl and theprotagonist is also a person who tries to resist the girl's charms but gradually gives in. The onee-san is a complete mystery...
