Sinchronicity is a six-part drama series broadcast on BBC Three in the United Kingdom. Set in Manchester, the programme is narrated by Nathan and focuses on the love triangle of him, Fi, and Jase. The programme is executive produced by Julian Murphy, who was an executive producer on Channel 4's As If and Sugar Rush and Sky One's Hex. Stylistically similar to As If, following a non-linear narrative, it also features ex-cast members Paul Chequer, Jemima Rooper and Mark Smith and, as such, can be seen as its spiritual successor. The theme tune is "Boys Will Be Boys" by the Ordinary Boys. The show was filmed in high definition and was re-run on BBC HD in mid-October 2006.

Heo Don-Hyeok is not interested in studying and he works to pay for his living expenses. One day, Heo Don-Hyeok saves Park Chan-Hong from a school bully. To pay for his rent, Heo Don-Hyeok asks to borrow 300,000 won ($270 USD) from Park Chan-Hong. Park Chan-Hong lends him the money, but that money was supposed to pay for his private institute tuition fee. After school, Park Chan-Hong now doesn't have a place to go.
