Korean actor Lee Jong Suk is at it again with the little but oh-so-swoon-worthy way he shows his support for his girlfriend, K-Pop idol IU.

Dispatch, as per Koreaboo, recently featured the couple, whose four-month relationship included outings for Christmas in Japan.

Also among the items was a recently released hat by designer brand Beyond Closet that was seen on model/actor Lee Jong Suk, who wore one emblazoned with "The Golden Hour."

Sharp-eyed fans were the first to notice this, as they remembered it being the same hat IU sported on her 2022 concert tour.

On social media, one fan wrote, "So sweet of him to hold support for her like this. To be able to do that, they really care for each other."

His appearance in support was a clear affirmation following the confirmation that the couple was dating. This relationship seemed to be solidified when Lee attended IU's concert in Seoul last year.

The couple also celebrated little moments that showcased their bond, and fans followed along.
