Once upon a time, there was a group of demons, among which demons A, B, C and D were the four most powerful ones. Devil A, Devil B are the handsome devils, Devil C and Devil D are of course the beautiful devils. There are as many female demons chasing Demon A and Demon B as there are ants, and there are as many male demons chasing Demon C and Demon D as there are cockroaches. But no, the beautiful woman and the handsome man are compatible only if they are together~ So after a series of ooxx@@##** events, Devil A fell in love with Devil C, Devil B fell in love with Devil D, and they lived together happily ever after~ Everyone is happy! It's really gratifying, congratulatory, congratulatory~..
