So uhm. I found this picture and I'm not sure if it's a real manga and if it's yaoi or what. I'm assuming that it's from a yaoi manga since I saw this image in a yaoi manga (though it was just used by a scanlating group and put it like one of those recruitment page)
If it's a manga, can you please tell me the title? Thank you!
