Soon after his marriage crumbled to tiny pieces, Chad began dating Kenzie after she appeared on the show as a cheerleader and just three months after being together, they were engaged.
This continued on for seven years, before they decided to break up.
After Austin joined the show as Julian though, they fell in love and remained in a relationship on-and-off for four years.
Yet, did you know that the show was also the birthplace of a number of relationships in real life too?
Indeed, many members of the cast gave love a try during their time of the show, some with more success than others.
Finally, they got together in November 2004 and by the time they were on One Tree Hill, they had already been together for five years.
They married in 2007 and welcomed their first child into the world in 2011. Which One Tree Hill cast member would you like to date?
One Tree Hill may have ended years ago, but the characters that made up the show still linger in our memories as we hope and pray for a happy reunion one day.
