Neighbours star Takaya Honda has teased that the long-running soap will soon be airing an unexpected storyline involving his character David Tanaka.

Keeping schtum on the details, the 34-year-old actor – who joined the show back in 2016 – told Inside Soap magazine recently that viewers have yet to see "peak David", and admitted how excited he is for everyone to see what they've been working on.

"I don't think anyone would predict what is coming," he said. "The audience, like David, are going to be really challenged by what unfolds."

Elsewhere in the interview, Honda discussed David's relationship with his husband Aaron Brennan (Matt Wilson), and how the pair will soon be seen disagreeing over what to do about the former's niece Abigail.

In scenes set to air this week, David's twin brother Leo will ask his sibling and his partner to take custody of his daughter, explaining that he can't cope with being a struggling single dad.

"David knows that Leo dealing with a lot, and that he just needs time," said Honda. "He can see that Leo is really struggling. But Abigail's welfare is of utmost importance, and it is a careful balance for David of trying to look after his brother while also making sure that Abigail is safe, too.

"Family is so important to David, so he would do whatever it took to care for both Abi and Isla – as challenging as that may be."

According to Honda, David and Aaron will be tested by the moral dilemma, but they won't allow it to break them – something that both actors see as hugely important, in terms of the message it sends to those watching at home.

"Matty and I work very hard to create a relationship as sold as Daaron's is, and we are very thankful that the couple has been left to approach situations together. David and Aaron don't always agree, but their love for each other is never questioned. I think that is a really positive thing to be putting out into the world."

Neighbours airs weekdays at 1.45pm and 6pm on Channel 5 (UK) and Mondays to Thursdays at 6.30pm on 10 Peach (Australia).
