Cardcaptor Sakura - Season 3 Episode 11

Syaoran's feelings for Sakura have been steadily increasing, though he still doesn't understand why, and Sakura remains blissfully unaware of it. Soon Sakura invites him to go to a teddy bear festival with her, Tomoyo, and Eriol. However, Eriol secretly traps Sakura and Syaoran on an elevator, where the two grow closer. Eriol then creates a large hole in the wall of the elevator, causing Sakura to fall through. Distraught, Syaoran calls out to Sakura by her first name for the first time.
