Why do I feel Deja Vu?

It's like I've climbed this tree before

Is this right?

I feel like I'm stealing something

I'll finish my mission tonight

I don't want to wait too long

I don't want to feel pain

No more pain

I slowly landed in Namjoon's room

I turned my flashlight on

I heard his soft snoring

I chuckled as I looked at him

As I looked around his room

It was all music devices, books and picture frames

Picture of him, his family, our friend group

And us, and by us I mean me and him

What shocked me most

Is the blue and frame next to it

And unknowingly, I shedded tears

His promisory note lies behind the glass

I read it, I read it all

Marriage?

He wants to marry me

"Y/N?"

I looked at him

Shock and fear plastered on his face

I sat on his bed and faced him

Tears flowing non stop from my eyes

He asked me what I am doing here

I grabbed the frame and showed it to him

He looked at it and gulped nervously

I can only mutter "explain"
