Warning: A clichè story ahead!This story is how Park Chanyeol became the reason why your frozen heart melted, why you smiled and why you cried. You made him the only exception of your promise. But will you have him forever as your Happy Virus now that you know who Park Chanyeol really is?"Can I be selfish for awhile?"Will it end the way you thought it would be? ForewordThis is actually my first time writing here in Asianfanfics because I only post my stories in Wattpad. In my 1 and a half year of spending my time in Asianfanfics, all I did was reading EXO fanfics. I thought of posting here my story, so why not? I hope you guys can appreciate and enjoy my stories on the way thank you! 사랑해, 엑소엘스!
