ML is sort of the protag... He take for granted that his love would stay with him. Like he never concern himself with listening to his lover words and concern. One fatal event he lost his loved one and acknowledge his errors while he embark in a journey to find his lover once again. Fantasy yaoi manga. Sounds tragedy but dont worry there's a silver lightning of hope at the end. ^^

Helppp. I need new read.. Please tell me something that goes like the seme taking the uke's feeling for granted at first. But in the end he realize it and feel sorry and beg the uke to come back. Not a tragedy please (i've read 10 years where i loved you the most and couldn't contain myself ). Thank you..
