This will probably go down in the annals of CCS as a landmark episode in the development of Sakura x Syaoran. Specifically, the latter’s feelings for the former begin to boil over to such an extent that he can no longer lie or obfuscate to himself about what she means to him.
While he occasionally asks either out loud while alone or in his thoughts something along the lines of “What’s wrong with me?”, much of his realization comes wordlessly as he watches Sakura both close up and from afar, be it during class, gym, music, or recess.
When Sakura invites Syaoran to join her, Tomoyo and Eriol at a teddy bear exhibit, he’s reminded of the bear he made but has yet to give to anyone. As he wrestles with his feelings after school he bumps into Yukito, who can quickly tell that Syaoran cares for Sakura very much, even if he won’t admit it.
Try as he might to shake off or run away from his feelings, they’re there, and they’re only growing the more time he spends with her. In fact, when he hears her voice on the answering machine (she had to leave two separate messages thanks to her tripping on Kero-chan’s video games), he listens to her a second time, just to hear her lovely voice.
Syaoran decides to play it cool the next day when the four of them hang out, keeping his hands behind his head most of the time as he watches Sakura having fun. The sequence is one of two montages that place Sakura and Syaoran in interesting visual framing devices decorated with autumn leaves signifying change on the horizon.
However, when Eriol brings up Syaoran’s homemade bear and Sakura asks if he’s given it to anyone, he becomes embarrassed again and runs off. Sakura chases him down as he enters the elevator, but then, as seemingly both another test for Sakura and a chance for Syaoran to be alone with her, Eriol locks them in the elevator.
After a period of awkward silence in the dark, Sakura starts to cry, so Syaoran cheers her up with a flame taliasman. She lays out her handkerchief and invites him to sit beside her so they’ll be more comfortable.
But then Eriol activates the next stage of the test, which involves the walls of the elevator falling away and Sakura plummeting down a deep, dark pit. Panicking, Syaoran calls out to Sakura using her first name for the first time.
Sakura rises up out of the darkness, having converted and used the Float card, and Syaoran simply gathers her into a hug, overcome with relief and joy she’s okay. Eriol ends his spell, the elevator returns to working order, and Sakura and Syaoran are rejoined by Tomoyo and Eriol.
That evening, Syaoran gets another call from Sakura thanking him for being with her during the elevator incident, as well as expressing how happy she was to hear him call her Sakura. In exchange, Syaoran gives her the okay to call him by his first name.
This is a big deal! Syaoran has finally stopped running and accepted that Sakura is special to him. It’s another crucial step towards a Clear Card future in which they’re officially a couple.
