Prologue: A New Tenant

She used to be only a pass by, but decided to stay in England for Mrs. Hudson.

She used to be only an audience, now she has no choice but to accept the invitation.

She was forced, but now making a willing move for the sake of Mary.

She used to be unimportant, but for Mycroft, she had no choice but to become the main character.

About John, he was the start of all this chaos. Without him, nothing would have happened. It was all his fault.

What should she do now?

"ring, ring, ring..."

"Hello?"

"Good morning! Is Mrs. Hudson available right now?"

"Of course dear, I'm Mrs. Hudson. What would you like?"

"Hi Mrs. Hudson. Is it true that you are currently advertising a unit for rent? Is the rent only 50 pounds per month?"

"Oh, yes! But the unit is in the basement, so it is a bit moist. London's weather, you see. However, I have already put in a heater! In addition, there's also a fireplace."

"To be honest, the only thing that I am concerned about is if it's soundproof. Will it be quiet enough?"

"Quietness... if you came here a month ago, it might be impossible....but you don't have to worry about it now. I'm the only one that's currently living here."

"That's marvelous! When will you be free? I would like to have a look around."

"Anytime, my dear. And yes, do you know the address?"

"221C Baker Street, am I right?"

"Yes!"

"What do you think? Does it suit your favor?"

"It's quite nice; quiet enough and the heater is working very well. Although I don't really know how to use the fireplace, I guess it still looks good. This room suits all my needs. It's just that sometimes maybe I would like to get some sunlight. Is that..."

"You are free to access the dining room on the second floor! The only thing that it's..um...a bit messy. The former tenant had left a lot of stuff behind and never allowed me to clean it up. He had a weird temper, you see, always annoying me, but I have always seen him as a son. Although he had already left, I still want the room to stay as it is. I usually open the curtains to let the sun in a bit. So, if you don't mind...."

"Of course, I wouldn't mind! After all, it's not easy to have a smooth life in London, especially when I've just come here. I don't have a lot of savings to allow me to waste around, I'm grateful for what I have right now."

"You are a really optimistic girl. And yeah, what do you want for your meals. I'm not quite good at Chinese food."

"Thank you very much for offering, but no thanks, Mrs. Hudson. When I work I don't really have a schedule, so I guess it is best if I cook for myself. May I ask where is the kitchen?"

"It's on the second floor, along with the with dining room. It's just that..... not only the dining room, the kitchen too is stacked with experiment equipment. Even the fridge is filled with... Keke, some human organs. But of course, I've cleaned it up a long time ago. Feel free to use the fridge, however, I can't guarantee that other dangerous things are still in there. So, it's best if you do not touch anything."

"Thank you for telling me, Mrs. Hudson!"

"Well then, Miss Su. Would you like 221C?"

"Of course, Mrs. Hudson. I would love to. And by the way, please call me Christine!"
