A cupsleeve event is an occasion where devoted fans come together to celebrate their favourite K-Pop idols' special moments, such as birthdays, debut anniversaries, album releases, and even army enlistments. Often hosted in cosy cafes, these events are marked by the centrepiece of their celebration: the cupsleeves. Every drink purchased at the cafe earns attendees a stunning cupsleeve adorned with a picture of their beloved idol. During a cupsleeve event, fans indulge in their shared passion for K-Pop music, play trivia games, take pictures with the decorations, and socialize while enjoying the food and drinks. In essence, a cup sleeve event is an occasion to fangirl/fanboy in unison, creating unforgettable memories. Originating in South Korea, this trend has spread to every corner of the world, making cupsleeve events a cherished and universal celebration of all things K-Pop.
