Treat the Second Male Lead Like a Stone

I possessed the body of the fiancée of the second male lead, who was madly in love with the female lead.
He sighed whenever he looked at me, and didn’t hesitate to throw harsh words my way.
“Marrying someone like you would be worse than death.”
Then go ahead and die, you arrogant duke!
It was a superficial engagement.
Neither Ricardo nor I wanted it.
Besides, I—someone who had possessed this body—had a world I could return to.
We’d both be better off going our separate ways.
But then, the second male lead suddenly started clinging to me.
“Are you planning to go to Leon? Or is it your so-called first love you always talk about?”
Was he nervous?
The hand Ricardo used to hold me was ice cold.
“I know. I know you love Leon.”
“…And you’re still doing this?”
“That’s why I won’t ask to be your first. First love or whatever—if that matters to you, go ahead.”
Ricardo’s eyes began to tremble.
“But let me be your last love.”
