Anica didn’t get burned. The goddess (forget her name) put anica in her body which had a huge birthmark (I believe) because she wanted to prove to Anica that she wouldn’t be loved by the ML & that he wouldn’t even know who she was.
The prince is the reincarnation of Anica past lover, anica was the goddess best friend. Richard is the reincarnation of the goddess ex lover who betrayed her. When Anica set her free she told Anica to kill the prince (cause she just feels scorned) and Anica of course refuses and she gives Anica 100 days (I think? I forget) before she dies, so Anica doesn’t tell the prince cause she doesn’t wanna give him hope. He low key knows it’s her cause he sees the signs.
hella spoilers (even if u read this i still this the webtoon is worth reading)
the only goddess was the girl trapped in the gate and Ancia was her bestfriend and everyone else was also a reincarnation but they were just human.
(past life)
the goddess was trapped by richard after he took her power. richard then killed the prince and held ancia captive.
(current life)
ancia goes inside the gate to save the goddess but the goddess was mad tbat she came late and made ancia exit the gate using hwr burnt up body, telling her she must kill the prince to get her body back. the goddess uses ancias body and the prince doesnt believe its the real ancia. stuff happens they all made up and lives happily i think
Okay so i heard that prince and Ancia, Richard and the sister are all reincarnation of goddess and gods that forgot there memories and the closing of the gate is keeping a specific goddess closed because she was betrayed and if i remember correctly i believe shes best friends of Ancia who hates the prince or Richard i dont remember and i believe Ancia fell in love with him and wanted to be with him but forgot her memories of being a goddess.
I also heard that Ancia got badly hurt and got her body burn and i believe she ran away and someone is pretend to be Ancia and the prince goes and looks for the real Ancia and i believe the goddess whos gets released from the gate is trying to kill the prince but before his going to die he begs to heal Ancia and is given a month to live and wants to save Ancia before his time. The goddess sees that he really loves Ancia and i believe she lifts the curse and heals Ancia .
Its a little messy me trying to explain but i heard it from someone who already finished reading the novel
