Paint my world (Sherlock X OC)

The rich client

On a chilling Wednesday I sat by the kitchen table with a coffee mug, wearing Sherlock's flannel house coat. He never denies me anything, John watson told me once that he doesn't like people touching his things, wonder why he allows me everything. I often stay inside the room when the clients comes, I'm pretty uncomfortable with strangers, apparently this detective and his people are exceptional. Yet this Wednesday I sat with my coffee mug at kitchen table, I closed the door, separating living room and kitchen so I don't disturb the client speaking to Sherlock, The client was a guy that much I've heard, from his voice. As time went by I got lost in reading Wattpad stories that my coffee went cold. Groaning in frustration I absolutely forgot they were working, instead opened the door almost yelling,
"it's cold can anyone pl.." I stopped as I saw the client sitting and remembered I interrupted a case discussion, that I interrupted a desparate man.... also pretty good looking man narrating his story, and appeared infront of him in my home clothes and Sherlock's huge house coat, with my hair being messy as usual, my mum calls me thrice just to remind me to comb my hair.
Everyone looked at me but I, at the client. His eyes seemed to be looking at me with the similar intention as was mine.
"Melody?" called sherlock startling me, making me finally look away from the client and look at him.
"y-yes?" I knew not what to say.
"coffee?" he asked about it gesturing to my cup.
"oh yes.." I stumbled while forming my sentence, "cold".
"can't you warm it yourself?" asked John watson facing me.
"but you two always do it...so..." I replied, but yes they were busy and I had to understand that I can do this simple job on my own, "it's okay I can do it".
Saying so as I was about to turn away the client called in utter desparation,
"good morning Ms... Ms Melody" he was quick to catch my name when Sherlock said it.
"good morning Mr..." I waited for him to say his name.
"Collins " he said, and I smirked in response while he continued, "Jacob collins".
"Melody Ball" I replied my full name as well.
"your coffee isn't going to warm itself" interrupted Mr detective again, rolling my eyes I looked at him,
"I was about to go anyway".
He gave a single nod and waited for me to go inside and close the door, next I only heard him saying to his client... or should I say Mr Collins to continue hi narrative. Mr Jacob Collins.
After he went away I found both the men talking to themselves.
"how was it?" I asked coming into the living room, "you took the case?"
At my enquiry Sherlock sighed and then responded, "unfortunately yes".
"hmm" I hummed as I sat by the study, "what's the matter with him?"
Sherlock again took some time to respond, " missing his diamond embedded watch, lost in office, has all the footage of CCTV, yet couldn't find anything about the watch, he says he's sure it's been stolen in the office and I doubt that so I took the case."
I nodded at it, "he did look very rich though".
"that's why you couldn't stop staring at him could you?" it came from the detective like a blow, did he ..?
"calm down, I wasn't even staring at him" I replied to which he laughed, a mocking laughter. John Watson shook his head and said,
"maybe you should give her the...."
"no" he replied, angrily "I won't, not now".
"give me what?" I enquired and no response came, wondering what it could be I spent my whole day, I was out looking for any job opportunity since I haven't heard from the previous company yet. I came home at seven in the evening, dinner was pretty quiet, Sherlock and John just talked to themselves about the case of Mr Collins amongst themselves where Rosie and I just listened. They were pretty gloomy I thought, so I didn't bother them much, atleast I hope I didn't. At bedtime I thought I'd ask Sherlock if he's mad at me, for he's never behaved like this with me, I sat at my side of the bed, waiting for him.
"got any job today Melody?" his voice asking me about my day and it gave me a sense of relief.
"no I hope they call me for an interview though." I said smiling, he again gave a single nod and didn't smile. Closing the door he sat on the bed and fumbled with his dressing gown pockets, pulling out a folded sheet he said,
"for you".
"what's this?" I asked, trying to be cheerful again.
"colli.." he paused, "Mr Collins told me to..." I noticed he stumbled and his hands shook a little, "to give his number to you."
My eyes were widened, he wants me as much as I do too,
"really?" exclaiming I took the paper, saving his number immediately I said,
"so he did like..." before I could finish my sentence I saw Sherlock already layed down, not facing towards me, he's tired perhaps, "me" I completed my sentence anyway. Then turned the bedside lamp off before drifting off. Next morning I woke and found the flat quieter than usual, with a message on my phone, from Sherlock, "we're out on case, Rosie's in school, breakfast is on the table, I covered it don't worry, just warm it up". it said.
All this time I've been with him, with them, this is the most lonliest I've ever felt, what has happened to Sherlock? I've to find out.
