Wanna One's Yoon Ji Sung has revealed another set of soft, wintry concept photos for his solo comeback.

The idol will be returning with a special album 'Dear Diary' on April 25, containing title track "Your Page" - a medium tempo track with sentimental acoustic guitar sounds - plus more. Yoon Ji Sung also participated in designing the special album as well as in photographing moments from his daily life to be included in the pages. 

Meanwhile, Yoon Ji Sung is expected to bid fans goodbye for a short while with his mandatory military enlistment, some time in the latter half of 2019.
