Help me

I started reading a webtoon and can’t remember the name.
Basically there’s a girl who was sent for marriage but she’s really sick. So her husband/ fiance gives her jewelry and she feels better but then it dulls and she gets sick again.
He lets her go live with her family and gives her more jewelry even bigger than the last time.
She feels something isn’t right and goes back to her fiances home only to find out he gave up his life to let her live.
