pls help look for this

pls bear with me, i really dont remember much except that it is BL and the setting is kinda historical, i dunno if its cultivation setting or martial arts, and the seme and uke are friends or maybe enemies from diff clans then someone die (idk if its the uke or the seme) but not really die, just pretending then they got together but it is secret to their clan coz they are in diff clan. Sorry if it doesnt make sense or if it doesnt match the real plot of the story coz i dont really remember the plot
