From xkazemg:
Lolly, our poor heroine who lives with her sick mother and a spoiled sister. Her live was changed when she encountered a handsome horse, Angel; Lolly eventually became the owner of Angel’s son, Happy.

Carl met Lolly and Happy, just as he ran away from his wealthy family. He stayed with Lolly’s family ever since. Lolly was left alone after her mother’s death and her sister left home to pursue for a better life…. Carl stayed by her side for support; romance started to develop between the pair….

One day, Lolly met her first “enemy”, Tania, who invited them to an equestrian competition. Just as Lolly and Carl dreamed of wining the gold medal riding Happy in the National Equestrian Competition, Tania & father have set their eyes on Happy and invited Carl for training in her horse barn. In order to win both Carl and Happy back from Tania & Co, Lolly has to win the next equestrian competition.
