So far the brothers do not end up together. It doesn't look like they will end up together either. Saying anything more would be too much of a spoiler. Go ahead and read this. It's a really good story so far. (๑•ㅂ•)و✧
The mystery of it all is captivating. As for the 2 bros, nope(last life they were). You'll come to love all characters(the 3 especially) and feel very sympathetic toward younger bro.
