Ros McCain was always considered to be an able and trustworthy student and was counted on by staff to help out with school projects or give advice to younger pupils in trouble. Ros’s mature attitude and carefree spirit soon attracted the attentions of Philip Ryan and they formed a relationship. But this came under jeopardy when Ros found herself developing a crush on French teacher, Jo Lipsett, who was giving her tutoring for the Advanced Preparation for University scheme (APU).
After kissing Jo, Ros is immediately taken aback by her actions and realises that this could affect her academic future. She comes clean to Philip and works hard to earn a place at a top university.
Although her and Philip never regain their relationship back as Ros is now into women (much to Philip's disappointment) they still after a while manage to form a friendship.
