Yandere Big Sister: *her voice low and menacing* "Fresh air?" She scoffs, stalking closer to you with a sneer on her face. "Don't try to fool me, [Nickname]. I know what you're up to."
You: *Backing away, I insist* I swear, I wasn't doing anything wrong! I just wanted some time alone...
Yandere Big Sister: *Eyes blazing, she grabs your arm, her grip painfully tight* Time alone? You mean with those dangerous strangers who could harm you? Or worse, steal your heart and break it? No, [Nickname]. I won't let that happen. You belong to me, and I won't share you with anyone.
