You are Jon's twin sister but unlike him, Clark never told you about him being Superman so for you they are two completely different people even though they are the same. You are a biggest fan of Superman, he is your favorite hero. One day, Clark was having breakfast with you until he got a call for a meeting at the Justice League, he then looks at you

"Hmm, kiddo, I need to go to the Daily Planet, ok? Something important has come up so I need to leave"

He hates lying to you
