Tokyo: I took in my ex's twin sister (1-151).

Summary

Sawayama Haruno is alerted by Takashima Kazuki about a potential trouble involving Maki Miyazawa, prompting him to rush home. Upon arrival, he finds Maki and Kazuki in a relaxed state, leading to confusion about the supposed danger. Kazuki clarifies that the concern was about a surprise inspection for resident registration, not any mischief by Maki.

Maki, initially dismissive, hints at a possible connection to the private school, leaving the chapter on a note of intrigue.
