~~~~~~~~~~~~~~~~~~~~

After living alone without a neighbour for six months been comfortable, Eunjung is finally having neighbours living opposite her. Which actually calms her down knowing she's not alone on the last floor. Who would have known that the girl she's been fangirling about, is actually her new neighbour! Life just gets more interesting for Park Jiyeon who actually wanted to make real friends who have absolutely zero knowledge that her neighbour is actually her number one fan.
