Ghadami's casting was announced in August 2014 before Kush was introduced by executive producer Dominic Treadwell-Collins in episode 4945, broadcast on 20 October 2014, as a friend of established character Martin Fowler (James Bye).

Kush was created to be a new main character who would "spice up" Albert Square and was initially billed as a hunky, energetic, funny, and kind-hearted market trader who masked a tragic backstory.

In September 2020, it was announced that Ghadami had left the soap after over six years, with the character being killed-off in episode 6257, broadcast on 19 April 2021, where he is pushed in front of an oncoming train by Gray Atkins (Toby-Alexander Smith).

Kush causes disruption on his first day by trying to drive his van down Bridge Street, but ultimately makes friends due his laid-back personality.

Afterwards, Kush confides in Martin Fowler (James Bye) that he is not ready for another marriage after the death of his first wife, Safirah.

Shabnam and Kush argue because he was not there for her and she plans to move to Pakistan, while he considers returning to Essex with his mother Carmel Kazemi (Bonnie Langford).

Shabnam rearranges their wedding, hoping that being married will help them gain custody of her daughter Jade Green (Amaya Edward).

Kush later advises his younger brother Shakil Kazemi (Shaheen Jafargholi) when he wants to have sex with his girlfriend, Bex Fowler (Jasmine Armfield), who is Martin's daughter.

However, when Kush is in the fish and chip shop after having a drink with Denise, Michelle Fowler (Jenna Russell) crashes into it, leaving him unconscious.

The pair decide to keep it a secret due to the complicated relationship Kush has with the Slaters and Fowlers, but when they are caught having sex, they admit to being together.

Kush is killed on 19 April 2021 after being pushed in front of an oncoming train by Gray Atkins (Toby-Alexander Smith) as he attempts to flee to Dubai with Whitney and Arthur after informing the police of a car heist that took place in November 2020 involving the Mitchell family and Shirley Carter (Linda Henry).

[1][2] Kush is initially billed as a "good guy" who is "funny and full of energy", but hides a tragic past underneath his "brash exterior".

[1] Executive producer Dominic Treadwell-Collins explained that the show's bosses had "had Kush in [their] minds for a while" prior to the character's announcement, envisioning him as "a new leading man to spice up the market and set some female hearts fluttering".

[2] Kush is established to have connections in Walford, namely Sonia Fowler (Natalie Cassidy), as he was once close friends with her husband Martin (James Bye).

[8] Thakrar revealed that the storyline of Kush and Shabnam's relationship was loosely based on the 1999 romantic comedy film 10 Things I Hate About You.

[6] Ghadami and Thakrar appeared on the ITV talk show Good Morning Britain to discuss the kiss after it aired.

[12] In August 2015, the show announced that their baby was stillborn, with a stoyline focusing on Kush and Shabnam's grief set to follow.

Kush and Shabnam have been through a horrific trauma in losing their baby Zaair and you can't really have a bigger test in a relationship.

[19] The affair would result in Stacey becoming pregnant at the same time as Shabnam, believing her fiancé Martin Fowler was the father.

[12][20] Kush and Stacey's son, Arthur Fowler (Hunter Bell) was born in December 2015, with Martin and Shabnam set to discover the truth in January 2016.

[21][22][23] Thakrar made an unannounced exit in February 2016, as the affair with Stacey caused her character to no longer trust Kush and seek a fresh start.

[24] Thakrar explained the reasoning behind her character's decision to leave was because "she knows too well you can only avoid your child's [Jade's] existence for so long, and actually it's very damaging.

"[26] The BBC Website detailed "Family is everything to Carmel – after her relationship ended badly with Umar, her husband, she is determined to ensure her 'little Kushy' settles down with the right woman".

[38] The suspicions would prove to be correct as Gray would kill Kush by pushing him in front of a train after accusing him of ruining Whitney's life.

[42] He continued that he would miss working on the show and that being a regular had been a "blast", concluding by describing Kush as a "silly sausage" with "too big a heart" and noting that "it's in the bits just before and after they call 'action' where my favourite memories are".

[42] Despite feeling sad about his departure, Ghadami admitted he was happy to be leaving with a bang and hoped it would be a shocking moment for audiences, commenting: "I'll be sad to see Kush go, but I've loved every minute of playing him and I have really enjoyed this final storyline, I hope it surprised a few people because I don't think viewers were expecting it.

[43] At the 2015 Inside Soap Awards, Ghadami was nominated for "Sexiest Male" and shortlisted for "Best Affair" with co-star Lacey Turner, losing "Sexiest Male" to Michael Parr (Ross Barton, Emmerdale), and "Best Affair" to Parr and Charley Webb (Debbie Dingle, Emmerdale).

[47] In 2016, Ghadami was nominated at the 21st National Television Awards for "Serial Drama Performance", but lost to Danny Dyer (Mick Carter, EastEnders).

[48] At the 2016 Inside Soap Awards, Ghadami was nominated for "Sexiest Male", losing to Charlie Clapham (Freddie Roscoe, Hollyoaks).

[56] Danny Walker of Mirror described Kush as a sex symbol, noting many viewers were pleased during scenes where the character was shirtless.
