All My Two-Dimensional Girlfriends Were Included in the Group Chat

Kasumigaoka Shiyu: "My ex-girlfriend manages the ***???" Yukinoshita Yangnai: "Brother-in-law, aren't I satisfied with having a sister?" Yukinoshita Yukino: "Aren't you already dead?" Sawamura Eri: "Come out, Oreki Kazuya." Back in time, because he was too happy, Oreki Kazuya got very drunk. When he woke up in the morning, he found a ** chat on his phone. So who can tell me, they are obviously two-dimensional characters, why can they now chat with me on their mobile phones? If you are famous, can I be your dad? How can we become a family? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
