well logic seems off not that this manga is logical but if they were husband and wife in previous life , how come they are saying they are not dating im mean do they not like each other ofcourse, they behave like old married couple who sleep together but dont even think about lewd. Just dont make arc like do i like her , dah you are her husband if you liked her in past how come you dont like her now man , wtf author better leave doing drugs while work or is author a mob virgin
