She is cute, have a nice body and good personality, but decided to create a reverse harem with a group of otaku, weird part is said otakus aren't good looking. The prostituition possibility seems to be out, I can't read JP but she repaid the tablet guy with a blowjob, glasses seems to have got a full fuck becaause she discovered a gravure magazine with herself, possibly done to keep his mouth shut. If she did that for someone that had a vague proof of her not being "pure" we can imagine what she will do to MC if she realized he was present when she blowed the first guy.
