Hi guys! I need your help in looking for a specific yaoi manga. I was not able to save it on my profile and couldn't remember the title or author anymore. It was a historical manga and the story went like this, a prince from Europe who went to some archeological site because it was his childhood dream to visit that place and met an army general (not sure with his rank) and the general decided to bring the prince to their place and of course they fell in love and the prince decided to stay on the seme's place. I just remembered it happened on a desert with an oasis. It's vague but I hope you could help me. Thanks!
