Is it normal to think about this after watching spirited away?

What it would be like if the two main characters, that is to say Chihiro and Haku, had sex. Assuming that they were older of course and I mean not the physical act itself but like what would happen to their relationship after wards. Like if after they realized that it was a huge mistake and because of it they aren't able to look each other in the eye anymore or even talk to each other even though he wants too but he can't because he still can't forgive himself for that night, I mean they both knew it would change things but damn it we loved each other so much and it just kinda happened I mean we were both to blame, we just needed each other and we didn't care....we were young...we had the whole world in front of us....we just wanted to be loved, but it changed everything...it just....changed...... I don't think that Mr. Miyazaki intended the viewer to think about that but damn it I can't deny that the first time I watched it that's what I thought about during and after the movie. I mean it was about 2:30 in the morning when I watched it and I was a little sleep deprived and also a little or maybe somewhat drunk....so.......yeah... Normal?
