I know this is a random ship but once you read the story you will get it. It's really funny actually, they both love piano and they both know Jackson Wang from Got7, AOA, Chanyeol from EXO and others so why not yeah? I'm sure I'm the very first author to write about this ship... oh and you might not know who Seo Kang-joon is, does Cheese in the Trap kdrama ring a bell? No? Well it's fine lol he is from that show and tons of others. I'll put some gifs so you get a feel.
