Help find romance manhwa

Can someone please help me find this romance manhwa- I believe its been a while since its been updated. It has 30 - 50 chapters.

So the FL is a sick princess that the imperial family doesnt care for, i am not sure but i think she has light blonde hair, anyway the rebells go against the imperial family and kill her and she reincarnates multiple times, so every time the same 3 guys barge into her place and kill her and she is like oh your here to kill me again but this time without your buddies (there are like 3 men going for ML). In the current timeline she decides to help the rebels against the imperial family in the hopes they wont kill her and all 3 of them slowly fall in love with her. The FL know about a secret door - that her uses. The door leads her to the twins/ children who have magic and she saves them from her brother. The brothers also different, there is like a crazy one etc. the FL is very sick, she fainted after the rescue mission. I believe it was supposed to come back for another season, can you please help me find it??? Pleasee

Thank you in advance
