( Credits to @AustinKelly526 for the idea ) Y/N thought he signed up for a normal job. Something quiet. Something safe. Something that didn't involve angry gods, sword-wielding tsunderes, and overdramatic kings with god complexes. But no. He's not a Master. Not a Heroic Spirit. He's... the therapist. Now trapped in Chaldea, Y/N has one mission: fix the Servants. (Or at least stop them from killing each other in the hallway.) From calming down Jeanne Alter's weekly meltdown, to dodging BB's chaotic matchmaking attempts, to surviving "family therapy" with Karna and Arjuna, Y/N's job is pure madness. No powers. No weapons. Just a clipboard, coffee, and sheer mental willpower. Pray for him.

A certain tsundere Hero King: "Mongrel, put down your sword and be my man!" "Stay away from me!!!" This is the sad tale of a pure-hearted boy who just wanted a normal life but was forced down the path of a scumbag.
