So I'm looking for a certain manga (or manhwa) whose name I've forgotten. However, I do remember the following details:

1) it was about this girl who had the ability to find really expensive items, like it was her natural talent.

2) there was this secretive group at school that this other main chara guy is trying to join

3) the group just goes to auctions or ways to make money

4) it's supposedly a group that will make you rich in the future or something like that

5) There is also a guy who is trying to join the secret group, and is rich. The girl who joined by accident is poor.

6) There are three members in that group, a pretty girl, smart boy and an eccentric leader

7) The main girl has the white (non colored in) hair that's usually like put up like mini twin buns?

8) The guy protagonist has black hair

Does anyone happen to know what manga/manhwa/chinese manga this might be?

is it M.A.X?
