Definitely, I wouldn't recommend you to read any Hwang Ri Mi's works b/c it's crap plot in later volumes and you would get annoyed quickly so try other titles from others' suggestions. 😳

ohhh, a good series is 'the prince's cactus' (sorry i don't know how to make it link!)
the girl isn't rich but her older sister marries this rich guy and the main character becomes an aunt to this guy who is the same age as her. it's really funny though because he is considered a prince (literally) and is really stuck up but she couldn't care less about his posistion and so they always argue. slightly cliche but light and funny
there's also 'ultimate venus' which is like arakure but the grandmother runs an actual legal business.
do you like ones where everyone is rich but the heroine? eg. ouran koukou host club

Wow, thats a lot. Actually I have read quite a few of them but there are still some i have yet to try. Thanks.

Well, i wouldn´t put all of Hwang Ri Mi´s in one pack. For example Hot Blooded Woman was really hilarious and enjoyable (yeah, it was little repetitive in the second part, but still good), but it´s truth that most of her other works were not quite up to it.

Ouran is great. I quite enjoy the hilarity of conftonting two different worlds. I would appreciate all of your suggestions with similar plots but what i am really looking for right now is something when the main heroine isn´t pushover and knows how to use her power.
