I just realized that I should've done this before I started the series.

Kissed by the baddest bidder is an otome game by Voltage Inc. It is a story about the MC being sold to an auction due to unfortunate circumstances. She then got bought by Eisuke Ichinomiya for the price of 20 Million (Idk if it's yen or dollar.)

That's the whole plot of it which is why, there is a woman being auctioned at the first part of the chat with them, and that is the MC. You, however, is Eisuke and Soryu's friend.
