The weekend part 1

"OMG ITS FINALLY THE WEEKEND!!!!" You think to yourself. You are both excited and terrified for today. Willow walks in with both trays of breakfast in her hands. (You and her like eating breakfast and supper in your dorm. Mainly because your embarrassed by Willows disgusting way of eating!) "Thanks, Willow." You say, grabbing the plate. "Where are you off to today?" Willow asks you.
"Oh, I er...... I-I'm taking weekend classes!" You say with discomfort.
"Pff! Nerd..." Willow says in a rather rude manner. "Well have fun, I guess..." You say goodbye and leave the dorm, thinking you might never return... (because you might get murdered by Yui Haraji!) Today, you are wearing a purple v-neck shirt and blue ripped jeans with a small diamond necklace hanging around your neck.

After a long journey, you finally make it to the mansion. (I have no idea where it is so please let me know in the comments of you do know) You go to knock on the doors but you hear voices:

Mephisto: You have to leave, dear. You can't seem to handle the fact that I spend time with other people. I mean, you hang out with Shura, she's your best friend! So go find her!

Yui: But Mephisto! I want to stay so I can make sure this woman doesn't do anything to you!

Mephisto: Oh, please! You just want me to look away for a second so that you could behead her! Yui, I can take care of myself, I raised you so I will be fine with this girl.

Yui: *sigh* Fine... can you please just tell me her full name, her age and what dorm and class she's in?

Mephisto: NO!! NOW JUST GO!!! We will discuss this later! You might want to spend the night at Shuras place. We might be here a LONG time.

Yui: Overnight?! Now this is ridiculous! Is this a one- night stand??

Mephisto: GO!!!

You hear footsteps getting closer to the door and you start to make a bolt for the end of the corridor until you hear Yui's voice "Hello, (y/n)! Where are you off to?" You stop in your tracks and are lost for words. "Um... I... urr... I-I'm lost! But I have found my way now!"
"That's good!" Yui says, smiling warmly. When you see her like this, she doesn't seem like the type of human to say such horrible things about someone. Wait.... is she even human?! Yui walks out of sight down the other corridor. You wait a couple of seconds to make sure she left THEN you run to the other corridor to check that Yui is gone. She is. You breathe a sigh of relief and knock on the huge doors. Mephisto opens it, sees you, smiles and says "Hello (y/n), and welcome to my mansion!"
