Bro, I swear this internet is trolling me... Right when the next page is about to get spicy, it literally fails to load and I had to refresh the website xD.
Moral of the story: don't divorce and don't separate the children.
Stupid parents, I bet their solution will be "we can't tell them the truth, it would be trauma, we have to forbid them from seeing each other without telling them why". And the two will look for each other even more.
I can only imagine what Kozue is thinking.
"Not only are my daughter and estranged son most likely dating, I also gave them my blessing, and even left them a pack of condoms...*sigh*...whatever, I'll die soon anyway, it'll be my ex-husband's problem."
