Yes, it’s Kim So Eun. Looks like she is rising to the top now ^^.
At last, she had a leading role in this coming movie with Yoo Seung Ho, which is 16 years of age.
The movie is of the mystery-thriller genre where a pair of high-school students played by Yoo Seung Ho and Kim So Eun gets implicated with a murder case and is a classic whodunit story as they seek to find out the killer within the stipulated time.
I remember seeing this guy before and after checking his profile, i knew it.
He was in Sad Love Song, playing the small Kwon Sang Woo in that drama.
Here are some photos of Yoo Seung Ho in Sad Love Song:
