The post leverages the 'Wonyoungism' aesthetic and popular character-based merchandise to create a relatable, low-friction shopping recommendation that feels like a personal diary entry rather than an ad.
Product placement
Miniso (a) ACTS: the video is a photo of the store's shelves and merchandise, and the text explicitly identifies the location as Miniso. Removing the name would change the context of the video from a specific store visit to generic shopping. Miffy (a) ACTS: the merchandise shown is exclusively Miffy-branded products, which are the subject of the creator's affection and the focus of the post.
