After I Agreed to Give Blood to Save My Boyfriend's Dream Girl to Cure My Husband's Terminal Illness, He Regretted It

When my wealthy boyfriend wanted to drain my blood to save his dream girl's life, everyone thought I would break up with him. Instead, I voluntarily inserted the needle into my vein and agreed to the full blood transfusion surgery.

For a moment, my boyfriend thought I truly loved him to death. He made an unprecedented promise that if I cooperated with the surgery obediently, he would give me a title and marry me.

But what he didn't know was that I didn't love him at all, nor did I want to marry him. I was only doing this to complete the system's task.
