How you meet
It is rather strange... But he just burst into your house, that resided deep within a forest unexplored by anyone, told you he was living there with you and over took the guest room as his own. You didn't object, being quite lonely. At around 5:30 you walked over to the guest bedroom door." I'm making dinner, do you want steak with mashed potatoes and gravy or tacos with Mexican rice?" You said to the door. It was silent for a moment before your new roommate shouted 'the first choice' through the door." Got it, I'll yell when it's done." You said before walking off.
Meet again
He would disappear for most the day before appearing again in time to hide in his room. You only ever saw each other at dinner. He would give you a passive-aggressive compliment, which you learned was as close as you were going to get to the real thing. But what surprised you was when you were struggling to cook one of the meals,(it was cubed steak with rice and gravy) every time you went to make the gravy the rice would boil over. After a while you were ready to scrap it and try a simpler recipe but before you could, giriko walked in and started to work on the gravy." I got this you just make the rice and the meat." He snapped. Once the food was done and you had sat down to eat giriko scolded you for not asking for his help. After that fiasco, he made you a golem to help around the house.

One day you were taking a walk when some...thing attacked you. You had never seen a creature who was going down the path of a kishen but you did know that thing wanted you dead. It's claws swiped at you, the only thing keeping it from urging you in half was the chain of a chainsaw. Now, I know what your thinking... ' giriko saved me' right? Do you really think I'm so predictable? No, the chain is part of you, but I suppose that is predictable as well. You wielded the chain like a whip, tearing the creature to shreds with ease. The soul flouted in front of you. Curious, you reached out to the red orb." This looks different than the blue souls I used to eat." You said aloud." It's been years since I ate a soul..." You continued, lifting it to your lips. You ate the red soul, making a displeased face." The blue ( human ) ones taste better... But the green ( white blood ) are the best... Yellow ( black blood )is too bitter for my taste." You rambled to the air, not being completely sane. When you turned around you saw giriko with a shocked expression. You stood there staring at each other for a moment before he stepped forward an nearly tackling you when he hugged you." Don't scare me like that, (y/n)." He growled into your ear. You hesitated for a moment before hugging him back." Sorry... Sorry I didn't tell you my secret." You mumbled into his shoulder. He rubbed your back softly, holding you tightly."... I'll forgive you... but only because I've been keeping a secret from you too... I'm a weapon, like you." He grumbled as he pets the back of your head. You hummed happily, snuggling into his chest in search of his warmth as a chilly wind blew past you. He wrapped his arms tightly around you, giving you the warmth you sought. He led your head to Rest on his chest so that he could see your face. Your eyes fluttered shut as you relaxed against him. He smiled softly down at you, petting your cheek softly. He hesitated a moment before pecking your temple. You smiled with a hum as you snuggled further into his arms." Your mine." He grumbled as he picked you up and carried you to your home." Course I am." You yawned into his chest.
Nicknames
Him: mine, babe, love(slips out occasionally but he also uses it to calm you down when you get mad at him)
You: Hun, love, master( when he's pissed at you and you need to calm him down)Cuddle
It was rare, but if you got him in an extra good mood, and could catch him off guard, you can usually convince him to cradle you. He'll complain for a while but eventually he'll just hold you, maybe even kiss you somewhere on your face.
