Opposites attract. (Rider x happy fun reader)

You are a very happy and nice inkling, you have a good team, lots of friends, a good life, but one thing is missing... you always try to make everyone happy and smile, but you came across an inkling who never smiles, does not like people, and hates happy people who think teamwork and friends will get them through life. So you make it your goal to make him smile by the end of the month, but will you make him smile, or will he be the first one that you can't?
