Ready your wallets! Actor Yoo Seung Ho, who suddenly enlisted in the army last month, will show his gratitude to fans with his first solo photo book.

This photo book, 'Travel Letter Spring Eyes, and ... ...', will document the 21-year-old actor enjoying his last vacation in Japan prior to his enlistment.

Yoo Seung Ho also opened up about his plans for the future, sharing, "If I go to college, I would've been a theater major, but I didn't want to limit the opportunities of my friends just to get my diploma. As I get older, I became even more determined as I observed my [charming and experienced] sunbaes who overflow with charms. I also decided to delay going to college because I wanted to finish my military service first."

The full photo book will be available for sale exclusively online on April 15th.
