I just happened to come across this video on the relationship revolving around Chris Redfield and Jill Valentine.
According to this user (BioPhilAlternative) there are 28 signs that Chris and Jill could be lovers. (I know it isn't stated out loud ... but you should know where I getting at with this one)
This video covers the details and the philosophy of romance and love between Chris and Jill.

You can feel free to agree "or" disagree with it if you wish. But after seeing this video, I truly believe that it could be possible that Chris and Jill are indeed lovers.
The problem is thar Capcom hasn't confirmed or denied anything about the relationship between the two. (Other than the fact that they ae "partners", that is)
Feel free to comment, and I do hope you'll enjoy the video.
