Mercenary/thief gets hired to infiltrate a noble hous and steal some stuff/kill the heir. He doesn't tho cause he develops feelings for him. The kid also becomes attached to MC even tho he knows MC isn't who he says he is. But really the story takes place in the distant future. Neither of them have moved on and end up meeting again. The noble kid is now 10x bigger and 10x more sadistic. They end up together i guess ¯_(ツ)_/¯
