Heartbreaking file footage shows Jonghyun 's SHINee bandmates talking about how their worlds would "collapse" if they ever lost a member.

The clip was shared on Twitter by a fan who has dedicated their account to the memory of the lead singer, who committed suicide this week.

The 27-year-old K-Pop star's fans have been in mourning since news of his death broke yesterday.

And this heart-wrenching footage has left them even more upset.

In the poignant clip, two members of the band sit talking about their friendship and how they'd feel if they ever lost one another.

One of the members makes a touching speech, saying: "I've thought about that, the concept of me leaving and looking back on myself.

"Of course, I thought a lot about my family. I really thought a lot about the members.

"Our debut which was in 2008 until now, how we've been together for that period.

"What if I were to suddenly disappear and you were to carry on activities without me?

"I would feel for the remaining members and I felt sorry to you all of a sudden. Thoughts came like that.

"How much time remains? So in nine and a half hours, I really disappear, the members remain without me."

And bandmember Onew asks: "Our memories of you will disappear all at once too?"

But he's told: "No we'd still have the memories. Why would the memories go? You want to erase me?"

Onew responds: "No, of course not. It's not something I've thought about.

"Thinking about it at this moment, I think my whole world would collapse.

"That's because we're people who have spent more time together than with our families.

"We see each other when we wake up, we're together until we sleep, then again when we wake up. We've been like that for 10 years.

"However I look at it, if this part of my life (you) were to go wouldn't my life feel empty?

"I would feel betrayed, thinking 'Why did you have to leave first?'"

Jonghyun - real name Kim Jong-Hyun - was a founding member of SHINee in 2008 and became one of the most enduring artists within the industry.

But the pressure to be seen as perfect while living life as a normal twenty-something appears to have taken its toll on the star.
