This story is a copy of mobile game called is it love,ryan. I love this game so much lately and the hero of this game reminds me so much of kai,so i have an idea to change ryan's character to kai.  And iam naeun fans, so i make her as a heroine,. I do not own the story or the characters, this story based on is it love series. I just want to share this story with kaieun as the main cast. Thank you... All right reserved to 1492 studio.
