can someone help me find this? pleasee-

Its a yaoi/bl manga.

the seme’s the prince of kingdom A, the uke is like a forgotten prince of the neighbouring country sent to kingdom A as a spy to kill the prince.

It starts off with the uke shown to be sold off to a noble (tied and everything like a slave), cute body that seduced the filthy noble. But once the noble took off the uke’s blindfold, there was a snake figure behind the uke and his eyes has some sort of power that curses and kills whoever he lays his eyes on, thats why he wears a blindfold often.

The noble dies- caused an uproar in the upper society but the prince hated that noble anyways but he was looking for the person that killed the noble cause apparently that murder method was well known in that kingdom, they just didnt know a small frail looking blindfolded man was the one that did it.

Uke tried to run away but his accomplice got caught so he’s stuck in kingdom A trying to hide but eventually got pitied by the prince and lives right next to him cause the prince took a liking to the uke, but uke’s next job was to murder the prince cause his family promised that if he managed to then they’ll finally accept him as part of the family.

But eventually they both fell in love but the seme has been denying that the uke was the infamous killer even though there were obvious signs sometimes.

Eventually everyone found out, uke tried to run away but drowned- when woken up he lost his memories but has swooned another man’s heart(merchant) . Both the prince and merchant are utterly obsessed with the uke and would do crazy things to get him by their side.

i only read up until that point. i rmb all this but not the title please help me find it
