Hoyland - played by Jordy Lucas in the soap - decides to take on a new romance after her failed relationship with Andrew Robinson (Jordan Smith).
The couple's constant arguing causes issues and conflicts between them and their friends, reports the Daily Star.
After the pair agree to start avoiding each other, she begins seeing Griffin O'Donahue (William Ewing) after he asks her out.
"Andrew pretends he doesn't care but he's not going to make it easy for them," a source revealed.
The storyline will air on Channel 5 in the UK from next month.
Jordy Lucas had previously hinted to Digital Spy that Summer and Andrew were to end their relationship in 2012.
