Yes, like the other person said it hasn’t been fully explained but it has been implied for example in the first chapters before Na Haeso discovered Minsheol cheating, he tried to be intimate with Haeso and she asked him to use a condom and he shouted “what for?! You can’t get pregnant anyway” or something like that. Afterwards Tae Ha finds a picture of a sonogram…. Sooo
im sorry im really not getting how the orange dude got to that point, i think im slow, could anyone like make it it in simple terms? cuz to me i see how much he does love her but for some reason i cant see as to how is he a bad guy before the cheating
