Most definitely, with their paths going to intersect at some point its inevitable like you said maybe not a full on scene but foreplay for sure. Im interested in seeing how early ryu finds out what's going on, im just hoping its not the very end of the game i'd like to see ryu's reactions to what the hell is happening in the village rather than "how could this happen

The end" I mean ryu literally has multiple things at this point telling him something is happening to the women in the village
I mean he cant stay oblivious for too long right guys.....(Ntr protagonist IQ decrease activates)
Personally, I prefer NTR where nothing is discovered, but in this type of game, part of the plot is that the NTR is discovered, and I think we are gradually approaching the point where Ryu realizes or, at the very least, has many suspicions that something is going on.
Something I liked about Ryu is that from the beginning he felt uncomfortable leaving Yui and Marin with Dukall and Enlai because he knew that both of them were perverts, and with the passing of the updates he still doesn't seem very sure.
We already saw how he didn't like Enlai being around Marin and even wondered if something was going on, and in the scene with Violet in the bathroom, he also seems to suspect that something else is happening.
But whether it's because of the spirit's influence or because Ryu is very positive and optimistic, he convinces himself that nothing is going on. Ryu also trusts Yui and Marin too much. He literally sees Marin giving Enlai a blowjob, and she tells him that the sounds are from the soup Dukall is eating, and Ryu believes her, haha.
