Urgent! We are looking for one of Prince Hanjin's dumbbells.

A photo uploaded to Weverse on May 25th. The owner of this photo is Han Jin. Han Jin ordered dumbbells for his workout, but the delivery arrived with only 5 instead of 6. Where on earth did that one dumbbell go? Does anyone know how Han Jin's dumbbell was liberated? I really want to find it for him right away.
