Summary: Ren is a high school student. He lived a simple life, too simple maybe. He had no friends except from the other workers in Venus cafe, the cafe that he works in for his allowance. He had no parents to support him anymore so he had to work, supporting himself. He had always wanted to have a simple life until he graduates from Pledis University.......But then an unexpected incident in a grocery store with an unknown guy changed everything. The strings of his life became complicatedly tangled with this unknown guy ----- the strings tangled in a knot that seemed to be too impossible to untie, forever. The start of hell it was for Ren.... or was it really ‘hell’? 

(sorry.. I'm not really good with summaries) XD
