So mc cannot merry Non-Virgin Girls damnn this game whyy.... 1 mistake and shes gone...You lost to wild bull and girl got preg? Well lost cause then cause MC doesn't go for non-virgin girls and putting them in the same room just results in her sleeping so romance events are gone. You can still increase her affection by checking on her when shes in a different room but doesn't mean anything. She'll have sex with anyone but the MC.
