Singer Kim Jae-hwan expressed his sentimental sensibility with a vintage object.

For two days on December 22nd and 23rd, Kim Jae-hwan released two music video concept films for the title song "THE LETTER" released on December 27th through official SNS and YouTube.

First, the concept film features ceramics, woodworking tools, wooden rings, and flowers reminiscent of workshops. In the second concept film, objects such as beds, watches, and letter envelopes are attracting attention along with a sentimental editing effect.

The short video alone heralded the deep sensibility and atmosphere of "I thought I forgot everything." In particular, impressive piano melodies are used as background music for the music video concept film, raising expectations for the full song.
