Brush up on your geometry, because the love triangles get complicated when you watch One Tree Hill online. The popular teen drama ran for nine seasons on the WB and The CW between 2003 and 2012, and in that span, created numerous romantic configurations among the characters.
The series is set in a fictional North Carolina coastal town of Tree Hill (hence, the title). The premiere episode introduces half-brothers Lucas Scott (Chad Michael Murray) and Nathan Scott (James Lafferty). When Lucas joins the high school basketball team, star player Nathan feels threatened.
Their heated sibling rivalry is further exacerbated by Lucas' chemistry with Nathan's girlfriend, Peyton Sawyer (Hilarie Burton). Also thrown into the romantic mix are Peyton's best friend Brooke Davis (Sophia Bush) and Lucas' best friend Haley James (Bethany Joy Lenz). Aside from their complicated love lives, Lucas and Nathan also deal with their messy parents, like their outright evil dad Dan Scott (Paul Johansson).
Later seasons see time jumps, as the characters transition to adulthood and take on marriage, children, career moves, drug addiction, kidnapping and more stories.
