It was only a test, an expieriment. And they did it. Because if you put multiple people to the test, how will they do? How will they love?  A doctor, a photographer, a model, a journalist, a singer, a teacher, and a college student.   Myungsoo felt a little lonely.  Howon felt a little greedy. Woohyun felt a little adventerous. Sunggyu felt a little needy. Dongwoo felt a little forced. Sungyeol felt a little curious.

Yeah, Myungsoo secretly takes pictures of Sungyeol when he doesn't know and posts them on his wall. Yeah, Myungsoo follows Sungyeol and hides when the man turned around. Yeah, Myungsoo really loves Sungyeol. But, Myungsoo is not stalker. He is just really in love.
