In the past few days, Ethan had been contemplating. Liana was the heroine of the book. If he remained on Liana's side, even if his life wasn't that of a winner, the heroine at least had plenty of plot armor that would keep her alive.
Look at Liana now. She repeatedly caused trouble with Helena. Yet, she was still alive because Helena considered Liana like a cockroach that would only annoy her but could be stepped on later. Helena didn't care and let Liana roam freely.
Duke Henry was the same way. He didn't pay attention to Liana's mischief. As if what she did would never bring the world to ruin. Wasn't all of this thanks to the plot armor provided by the original author?
When Liana confessed her love to Ethan, there was a whisper in Ethan's heart to turn and help Liana instead. There was a whisper to restore the victory for Liana.
However, love made Ethan's heart side with Helena once again.
Ethan's eyes, always gazing at Helena and only Helena.
