The Plot:

Choi Minho works at an instrument shop in Seoul, that doesn't have many customers.

He once had a girlfriend called Im Yoona, that broke up with him because she fell in love with someone else.

One day at the instrument store, he sees this girl, who wants to buy a piano.

He thought she looks a lot like Yoona and kind of hopes he will see her again.

Few days later he finds out that someone is going to live next to him.

He gets curious and wants to know who that person is, so he knocks on the door.

When the door opens, he finds out that it's the same girl that he saw at the instrument shop and that her name is Kwon Yuri.

Your choice on the story:

Who is the guy Yoona fell for?

1. Lee Seung Gi

2. Someone from SHINee

3. Someone else

Does Yuri like Minho?

1. Not at first

2. Not at all

3. Yes, since she first saw him.

Some scenes that I think would be a good idea to have in the story, but you don't have to write this in your story: 

@ a romantic kissing scene (Maybe a kissing scene where they are kissing, while playing the piano together)

@ Yuri playing the piano

@ Yoona meets Yuri 

@ other SHINee members and SNSD members appearing in this

Ideas for titles:

Piano Girl

Instrument Seller

You Look Like My Ex

My Neighbor

(You can find better titles.)

I hope you like your plot.
