Interestingly though they and their respective love-interests only appear to affect each-other.

Man idk why this author just doesn't go make hentai and be done with it.
These plot devices are just plain stupid like.. hentai plot stupid.
I'm done with this.
something tells me he is one of Yuuki Rito's Cousins or some other family relation with his ability to cause or happen to run into these types of situations.
The author intentionally publishes this as smut and not hentai because despite all the ridiculous sexual scenarios this manga actually has some level of believable romance development.
