Of course, it's not the best option, but if the cheating scene is so important for understanding (even though it was clear before that they caused him pain), let it be as it is, since it's the past and Sara, as I understand it, is not LI, so yes, it was not very pleasant to see. Of course, Mark's appearance doesn't make the situation better, but I hope he doesn't stay in the game for long. And as I already said, MC's behavior is strange they treated him like that, and he still kept the photo and didn't even block them from his contacts to cut all ties. It's all a bit strange.
