On the 16th, an article titled "Lee Jong-suk fully wearing IU's goods" was posted on an online community.

The post contained a picture of Lee Jong-suk wearing an IU goods hat in private. The hat worn by Lee Jong-suk was sold at IU's solo concert 'The Golden Hour: Under the Orange Sun' last year.

Previously, IU also showed a picture wearing the same hat on her official YouTube channel. This hat was sold for 25,000 won and is currently sold out.

In another photo, a man who looked like Lee Jong-suk's mobile phone accessory caught attention. The 'Grip Talk' he attached to the back of his mobile phone is one of the official MDs for the 2023 Year of the Cat released by IU's agency. It was sold for 15,000 won from January 16th to 27th, and this product is also sold out.
