Jessica call him 'Devil Choi' ever since they got married.He is a grumpy, moody and jerkest devil in the world.  But time comes, Mark Choi said "I'll be better". Is it really possible for a devil to be 'better'? Two lives, two different people becomes one.     It is a TOPSICA story (Choi Seunghyun and Jessica Jung) with the SNSD members and Bigbang members. Mark Choi is Choi Senghyun XDDD
