Arc one is about living. In short MC had no freedom and ML was his light. He freed himself of worries and followed MC only to be betrayed later. He killed the ml's unborn children and suffered mental torture. In the end he killed ML himself. Later he ascended the throne living alone and dying quietly. But in extra some misunderstandings will be unfold. It is sad story but nothing compared to second arc.

In arc 2 MC was fallen noble's only son who lost his father and mother. He became prostitute and his personality was terrible. On day he met naive pure and sincere fox demon. But he was blinded by greed and wanted his internal pill (dantain) to stay beautiful forever. He pushed ML to his death. But still ML loved him dearly can't bear to hate him and willingly give his life to him. His years before death was torture. His entire being vanished never to be reborn or reincarnated. MC later regretted but his feelings for ML wasn't love. He just missed ml's pampering and sincerity. He engraved ml's bone before and after ml's death he payed back for that. He became ugly old man with disfigured face and blind eyes. Wanted to die but can't die. But it seemed like he in the end died.

The stories are actually connected though! End of Arc 4 starts to show it. Love triangle, more like a love chain. Try to remember the named characters! They're important.

A love square: between Person 1 who's in love with the Good HALF soul of Person 2, the Bad half of Person 2 who wants the entirety of Person 1's love, and Person 3 who wants Bad Half of Person 2's love. So yeah, Person 2 is kind of 2 people in one lol.

Although at first, they don't seem to be connected, except the bone engraver, all the arcs are connected. They revolve around the same peoples' reincarnations.

You'll pity each and every single one of the characters. In the end, all of them had done something wrong, yet it feels almost impossible to hate any of them. They get what they deserve, even worse at times. Sometimes it'll even make you think about all the 'what ifs', 'if only this hadn't happened', or perhaps, 'could things have been different even if this hadn't happened?'

Like, I really really felt bad for the bone engraver, Chang ge because I felt that even if things had gone differently, even if all those bad things hadn't happened, he still wouldn't have been able to have a happy ending. Even his birth was kind of a mistake. If there was no bone engraving, he might not even have been born.

You can't blame any of them for their mistakes. They all had a reason, though that didn't exonerate them. All of them got their bad endings. In the end, no one got anything.

At the end of each arc, I'm like, "why did this have to happen, it was going so well?" It'll give you hope for a good ending (even though you already know it won't end well). It gives you hope and then crushes it. At times you'll feel happy (very very rarely) and at the next moment, you'll be drowning in sadness. The third arc even made me laugh at times. But it's like the calm before the storm. The sweeter it is at first, the more painful it'll be later.

Everything gets uncovered in the seventh arc and it ****ing hurts when you get to know the whole thing. I simply couldn't stop crying at the end of that arc.
