What an amazing chapter. Too bad this kind of thing only happens in fiction/fantasy stories. I'm so jealous of Yuya-kun, having a future wife who loves him so much and proactively making his partner fall in love with her. It seems very difficult to experience such in the real world.
Additional info:
I am used to seeing manga like this and I also understand the understanding of the culture of shame, especially in Japan or generally in Asia (Maybe, i don't know. Lol), which is different from other continents. So in my opinion the choice is just enjoy it/forget it/leave it.
