SHOULD DEFINITELY LOOK FOR BIGBANG!!!....Haha just kidding;; Well I think songs from BTS, BIGBANG, Block B, Mamamoo, 2ne1, EXO, Red Velvet, SHINEE, F(x), SNSD, Super Junior, WINNER and BEAST could be...well VIXX and Infinite would be a good inspiration too....or Gfriend if you like school stories haha!!! Oh I just thought that you might love older songs from TVXQ before 2009, or any ballads you could find around youtube! Good luck with your choosing and have fun!!
