Read manhwa I Thought I Didn’t Have Long To Live! / Time Limit / I Thought It Was Time!
Lariette, princess of the Blanchett family, who was diagnosed with the disease had only three months to live.
I was dying anyway so I decided to do some crazy things.
Firstly, living with a fiance who is older than me and there is no affection between the relationship.
Second, date Asrahan, the monster duke for 3 months! As soon as I decided to run away from him, I discovered something.
The truth is that I didn’t have the disease and only lived for 3 months.
“Lariette, didn’t I tell you?”
Asrahan said with a savage smile.
“If you run away, you will be responsible for any consequences”
