The Grace Timeline can only be read officially at Webnovel. These books link to Webnovel. As of now, there is no official paperback versions of this timeline. This timeline is very, very similar to the Judgement Timeline. Only the ending books are different.
Grace Timeline Ending: Two Couple Pairs actually die but the main characters get a happy ending.
Judgement Timeline: All Couple Pairs are safe in the end, but our main characters are far from okay.
The Grace Timeline is under the author Serena Walken.
The Grace Timeline is written in the original serial style it was first published under. It was remastered for editing/concept ideas. This means that couples came in and out of focus chapter by chapter until their story reached the end, so there was always more than one love story going on. None of the other timelines performed this function. Grace Timeline is completely considered Closed Romance.
