It will probably be similar to what they did in HHA.

In HHA, when Mara left, Noa came, a completely different character, and became Jerome's love interest. Mara and Noa are completely different, but Noa is what would've happened to Mara.

In HOA, KT will be in Nina's place, but will be 2 different characters. Although KT's love interest will most likely not be Fabian, but Eddie. Or if Willow comes in Amber's place, they are 2 different characters, but Willow's love interest will probably be Alfie, which is the same as Amber.
