Kyuukyoku Venus

Yuzu was afraid she'd be completely on her own after her mother died… but when she finds out she's not, she doesn't know whether to be relieved or annoyed! A sudden meeting with her long-lost grandmother reveals her status as heiress to a wealthy estate, but Yuzu isn't at all sure she wants anything to do with it.
