With only three months left before his long-awaited departure back to space, he meets Cheon Song-yi (Jun Ji-hyun), a famous Hallyu actress who suddenly becomes his next-door neighbour.Slowly, he finds himself entangled in Song-yi's crazy and unpredictable situations, and finds out that she looks like the young girl he fell in love with in the Joseon era.

At night, when they slept in a hotel, Soo-ji promised that she would send him 1000 letters, daily, during his entire term in the army, by presenting a red card with the number "1000" drawn on a red heart.

This act affectionately touched Ho-jae and he gave her a hug.

hopefully theres more promising kdrama in the future. from 1st up to 16th is so damn exciting and intriguing episode! heartbreaking that she going to arrest Lee Dong-Joon! The focus has always been about finding out the truth and going after all those who are corrupt.

And also for the people who keep asking for romance, please remember that romance is not the main focus here.
