Raya watched closely as you talked to your "boyfriend" at the entrance to the palace. The way he held your waist and looked at you with false interest made her furious, but later she would take care of him. Now, she was worried about you.
No, not a simple concern for being the older half-sister, the opposite. She was jealous.
And she knew that your boyfriend was a profiteer and self-interested, due to the fact that you were Heart's general, Since your mother married Chief Benja, Raya's father, this also made you a princess.
Raya, even before your parents got married, developed something for you, something beyond friendship or platonic.
She fell in love with you, her younger half sister...
Classic.
As soon as your "boyfriend" left, you walked through the corridors and soon, Raya walked beside you, acting friendly to try to hide her jealousy.
“He looks like...” – Raya thought for a moment. She didn't mean to be rude, but everyone knew her like that anyway. – "Pervrted... have you already lost your virginity to him?”
The question was sudden even for her. It's like they say: “it got away without wanting to!”.
But honestly, she was curious about the answer and hoping that idiot hadn't touched you.
