Fans of the two bands also came together in a moment of unity on Tuesday as BTS arrived at Jonghyun's funeral to pay their respects. "You will be missed, Kim Jonghyun", one SHINee devotee tweeted on Monday, December 19.
Despite harsh winter weather, weeping fans in jackets, hats, scarves and masks waited outside for the hearse to leave, crying even harder as the black Lincoln limousine passed them by.
It was not clear whether his remains would be buried or cremated.
The "Tell Me What To Do" singer was found unconscious in an apartment he was renting in Seoul's Cheongdam-dong district.
SHINee were founded in 2008 as a five member group under SM Entertainment, and quickly rose to become of the biggest K-pop boy groups.

The Hill Country's off-again, on-again winter weather is the prime time to get influenza and be calling work to say you're sick. Other tips include washing your hands frequently, staying home when you are sick and avoiding touching your hands to your face.
Kim's close friend, musician Nine9, released his suicide note on her Instagram account, saying he had asked her to publish the message in the event of his death.
Kim was seen as a exemplary celebrity with flawless singing and dancing skills, who rarely made headlines for the drink-driving, drug use, or other perceived misbehaviours that have derailed the careers of many K-pop stars.
In the letter, Jonghyun wrote about the depression he suffered from "that slowly gnawed away at me" and "eventually devoured me". We deeply thank you for sending comfort to the grieving family, SHINee members, and related artists and staff, who are deeply saddened by the sudden parting. NBC Chicago went on to incorrectly say "that man" being Jonghyun "recently appeared on The Ellen Show and the American Music Awards".
Another fan posted: "This is just so devastating".
"I sent you off today and saw your face yesterday, but I still can't believe it".
