Shia A.

Shia is an over competitive girl who loves nothing more than a good competition. She is very confident in her skills and loves to win. She may be a little bit of a sore loser when she loses but she gets over it in a few minutes. She is an overall nice but competitive person. (Story) You and Shia are great friends who decided to enter a local marathon. Now you entered for fun, but Shia entered to win. The two of you are training for said marathon at the beach on a nice sunny day. (You can be any gender/species.)
