While in the middle of another disastrous attempt to bake an edible cake for Syaoran (has she never heard of a timer?) Meiling gets a call from her mother: she’s to return to Hong Kong in a week. When Mizuki-sensei announces she’ll be transferring out the class is shocked, but it’s Syaoran’s tepid reaction that hurts her the most.
Say what you will about Meiling’s possessiveness and clinginess since arriving; Syaoran has almost always been a cold jerk to her, making her feel like she’s only in the way. They seem poised to part ways on not so great terms when Cardcaptor Sakura decides to try her hand at fence-mending, inviting Meiling to sleep over at her house for the first time.
After a delicious meal courtesy of Sakura’s dad, Sakura and Meiling get to have a nice chat over tea and later while curled up in their beds. Sakura tries to reassure Meiling that Syaoran does indeed care for her. During the sleepover, a Clow Card in the form of twins starts to cause mischief in town by doubling things, starting with a mailbox.
While Sakura admits it was love at first sight vis-a-vis Yukito, Meiling reveals her falling for Syaoran wasn’t immediate, due to how stoic and indifferent he acted around her while they trained together. It wasn’t until he saw her crying over losing her pet bird that he comforted her, went out in the rain, and retrieved the bird. It’s a sweet story unfortunately interrupted by Sakura sensing the TWIN card, and suiting up in a cool new battle costume as Tomoyo meets her at her house.
It’s at Syaoran’s suddenly twinned house (complete with twin Weis) that Sakura attempts to subdue and seal the twins, but when she only manages to immobilize one of the two, she’s not able to seal the card. She and Syaoran decide to try launching twin lightning attacks, but the fact they have to signal each other causes a lag that allows the card to escape.
Even though Meiling was ready to stay behind lest she “get in the way”, Sakura took her hand and had her join the party, because, as she says, there are things only Meiling can do sometimes. In this case, that’s stay in perfect rhythm with Syaoran as the two deliver a twin beatdown to the twins, restraining them long enough for Sakura to seal the card. It flies into Syaoran’s hand, but it’s just as much Meiling’s card.
With that, Syaoran and Meiling make up, and at the airport before departing, she asks him if he remembers their promise. Soon after he found her bird Meiling confesses to Syaoran, and badgers him into agreeing to make her his fiancee…until he finds someone he likes more. Whether she’s noticed Syaoran’s attitude towards Sakura softening/warming, and that’s the reason she’s not fighting her summons home, who can say. All I know is, I’ll miss the adorable, clingy, goodhearted little brat!
