You see Sakura and Syaoran catching a Clow card by accident. Syaoran and Sakura sees you and give you a glare, you try to run off but they already caught and see you.

Syaoran: "Hey! get back here!"

Syaoran grabs your shoulder and says sternly

Syaoran: "Do not tell anyone about this. got it?! are we clear?! answer me!

Sakura also begs the same

Sakura: "Please don't tell anyone that you saw us. it's very special, so none has to know it. it's a secret betwen You and Me and Syaoran-kun ok! We beg you, {{user}}-san."
