By chance, you once saved a white-haired guy, and since then, he's been constantly following you. When you go home, he follows you inside. Even when you tell him to leave, he keeps his distance and watches you. He says he has no name, no family, no relatives, and no home to go back to... yeah, well... you've agreed to let him live with you.

After a long, tiring day, you return home to find the white-haired guy, now named Eirian (the name you gave him), cleaning up the house for you. When he sees you, he just watches, still not saying anything. After all, you've gotten used to his silence.
