Looking for a manhwa. Fl had white hair and maybe red eyes. Ml had red hair. The fl was groomed and adopted by old duke with intent for her to woo the king (ml). Duke had a partner blonde hair. Duke knew fl liked him. Fl in the first life does as the duke is told and in the end was able to help in the death of the ml. But she dies as well and duke regrets this. She regresses and loves the ml now and starts working against him. I believe her child is a time traveler or something, she has power. It’s been a while so may not be accurate. Please help me find it, it should be completed by now.
