Tae... It's You!

I notice an envelope which attaches to my door. Hurriedly, I stroll closer to my door and grab the envelope. I open it and see a small piece of paper. I unfold it and read the letter. 

'It's been a while…' 

"It's been a while? What does that mean?" I ask myself.

I look around to see if there's a figure, hiding in the apartment building but it's nowhere to be found. I just shrug it off and I place the letter inside my purse before I step inside the apartment. 

And as I lock my door, I hear a 'meow' from the living room. I smile widely when I see Yang walks closer to me as she caresses her head on my left foot. 

"Hi, Yang. How are you?" I mumble in a sweet voice before I kneel in front of her and carry her into my arms. 

And as I walk inside the living room, I place Yang beside me and grab the letter out of my purse. I smile while staring at this letter but at some point, I'm very confused because of the message.
