Kind and somewhat naive, Sandie is easily upset when things go wrong but strives to develop her independence.
• Conor Martin (Cillian O'Sullivan), arrives in Belfast all the way from Cork. Tall, dark and mysterious, he captures the attention of Sandie but must come to terms with his true self. One of the lads, he's always up for the craic and enjoys himself most on the football field.

She will fiercely defend her friends but tends to put herself first.
• Christopher Leech (Ryan McParland) A geek at heart, Leech (as he prefers to be known) desires acceptance and popularity the most and will do anything to attain it. Loud, boastful and slightly wild, he's always up for adventure and fun. Leech's nemesis is childhood bully Gary Meadows and he has a secret crush on fellow gamer Carly.

He is deeply ambitious and independent, ready to accept any gainful opportunities that come his way. He eventually decides to leave for New York but still pines for Conor.
• Carly Bonner (Lauren Ellis-Steele) (series 3, recurring previously) Hailing from Glasgow, Carly is a friendly, caring and insightful girl. She quickly develops an attraction to Leech based on their mutual love of gaming. Loyal and committed, she soon befriends the rest of the gang but is frustrated by Leech's apparent fickle ways.

• Liam Madigan (Dermot Murphy) (series 3) Liam crashes onto the scene just as the friends are preparing for their final semester, taking Danny's place in the house.

He eventually moves to Dublin.

Christine Keighery, of the Crossmaglen Examiner, praised the show for its local talent - "Written by, filmed in and starring actors from the North, the series is being hailed as a, long overdue, return to home-grown drama."[4] However, Lee Henry, writing for Culture Northern Ireland criticised the series during its first season, in comparison to long-running British soap opera Hollyoaks, for aiming a teen drama at an adult audience.[5] Likewise, the News Letter drew comparisons with Hollyoaks but also commended the local talent, describing it as "...exciting because it’s a Northern Irish drama - a rare and therefore precious offering."[6]

By the third series, Joe Nawaz, writing in the Belfast Telegraph, generally praised the series as smart and youthful, but criticised some of the dialogue and the attempt to "re-imagine Belfast as a kind of fantasy cosmopolitan postcard destination."[7]

Jamie-Lee O'Donnell, who played Derry character Eva Maguire, went on to star in Channel 4 sitcom Derry Girls, also set in Northern Ireland.[8]
