Some say that the more time you spend with a person, the more you look alike. This is what happened to Park Shin Hye and CNBLUE's Minhyuk in their recent selca together.

On October 30, Minhyuk posted the picture on his Twitter and said, "A couple starts to look like each other... No, it's not like that! Childhood friends Cha Eun Sang and Yoo Chan Young look good together. Eun Sang, never give up! Don't lose to the heirs! Everyone, make sure to catch the seventh and eighth episode. Lee Bo Na will check!"

Wearing their Jeguk High School uniform, the two cast members posed together for a photo collage. They showed off a variety of facial expressions, looking like real-life close friends with the warm relationship they seem to have. At the same time, they gained attention by being able to pull off youthful faces even in their twenties.

Also posting a selca in his Jeguk uniform is ZE:A's Hyungsik. He tweeted, "The Heirs will be showing today! It is also the day I practice for the ZE:A concert! It will be on November 23 at the SK handball gymnasium. Hope many would come!"

Catch them wearing their adorable uniform in "The Heirs" every Wednesdays and Thursdays at 10PM KST.
