Oddball, Love Equation

[Uma Musume fanfiction, female reader insert + second-person POV + solo and ensemble pairings + sweet and angsty + OOC warning] Love is a difficult question to solve, so I choose to treat this elusive affection as an unknown. Each variable represents a different element of romance, and each constant symbolizes the feelings that never change. I turn love into an equation, which I call The Love Equation. May I have your heart alone, and stay with you until our hair turns white. Your love and hatred, joys and sorrows with them. “Nice to meet you. It's been a long time.” “Surprise! I'm not some helpless sweetheart.” (These are all short stories. Only Volumes Two and Three are serialized.)
