Help!

So, I have read a really good manga (or is it web-manga? Manhwa? manhua?) about a man who was looking for his relative (his brother?) that got lost in some mountain. He hired two guide, both males. One of the guide has wife and kids if I'm not wrong. The story is about their journey to find his brother. And when they're on their way, they found out that his brother is a spy (or not, But if I'm not wrong, the clues point out that his brother is a spy but never really confirmed.) it's not completed yet and if I'm not wrong, it's shounen-ai. I really wanted to read it again, so, if any of you knows, please tell me! Thank you!
