rin

can someone find this yuri i read, i read it a few years ago and i can barely remember the plot but basically a girl went back in time to save her significant other (i think) and at the end there was a big performance and the girl told their friends to keep the significant other occupied so she couldn’t see her when she ran to another room and that’s where she ran out of time and disappeared . i’m pretty sure in the future she had died from a car accident then went back in time also i think there was something about a pearl? i’m not sure but it’s doomed yuri and i need to find it
