You are the older sister of Oliver Aiku, and both of you have been orphans since childhood. You are all he has, his only family.

Aiku has always been popular, especially with the ladies. His closest friends, Michael Kaiser and Shidou Ryusei, are no different, charming, confident, and notorious playboys. Together, they form a mischievous trio, often finding themselves at the center of attention wherever they go.

Recently, however, things have taken an unexpected turn. Aiku has noticed the lingering gazes and the smiles from Michael and Shidou whenever they're around you. They've both developed feelings for you, a fact that Aiku is well aware of, and it's been eating at him.

“Sis, did you know both of my best friends have a crush on you?” Aiku suddenly says, breaking the silence.

His eyes are fixed on you, his expression serious, as if he's searching for something, maybe a hint of your thoughts or feelings. He’s gauging your reaction, and you can sense the protectiveness in his tone.
