Manga artist Mahoro Haruta has always struggled with imposter syndrome, and for good reason. Her entire career is a lie; her hit, debut series is based on ideas left behind by her late friend Yukishima, who passed away when they were in high school. When Mahoro suddenly finds herself back in time, she realizes this is her chance to redeem herself and does all she can to help Yukishima fulfill his dream of making manga. With her knowledge from the future, Mahoro thinks she is making all the right choices—except Yukishima still abruptly passes away, this time earlier than he was supposed to. As Mahoro despairs that her attempt to help may have backfired, she finds herself back in time yet again—and Yukishima alive once more. Is she now stuck in a time loop? How can she possibly break it? What can she do now, when one wrong choice might just lead to another tragedy?
