Thank you so much! =D I'm so glad you enjoyed this.

The way I see it, Shuji was not cheating on Yuriko since he had asked her if he could be with Nino and she had agreed - at that point, she was pretty angry about the fact that he was gay and hadn't told her until they'd ended up starting a family, but the relationship with Nino was never behind her back. In fact I think Yuriko thought having Nino come stay with them was the biggest perk of her marriage with Shuji... =)
