Sakura and Syaoran were chosen by Miss Kaho to act a play which was 'Sleeping Beauty'.
Knowing that Yukito would watch their skit, Sakura suggested to Syaoran to practice the skit together the next morning. Syaoran agreed. During the practice, just as Sakura was about to kiss Syaoran, a strange power surrounded them. It was a clow card.
Both got up and fought with it. Finally, after much fighting, the card flew to both their hands meaning both of them are its owner. Sakura gave the card to Syaoran as Syaoran gave his card to Sakura the previous time.

So romantic~~~~~~~
