Time reversal

Hi
This story is your typical time reversal manwha where the lady does not marry her first love who she never talked to in her first life and ends up in an ?abusive marriage? and later finds out that her first love died and she goes to the funeral which is at a church or something so she asks to be reborn? She goes back like 10 years or so and meets her first love at the LIBRARY and tries to initiate something. I heard this story is completed now and wanted to read it.
Thank you!
