Yung Lean explains why he chose to distance himself from Ye:
"Kanye's mentally ill. I've been there, and I feel for him. [...] I can't defend him, it's a mentally ill person, who still did 'Flashing Lights.'"
"I haven't seen him for a long time now, because it's too much. [...] The best thing I could do is not make a song with this man."
"You can really be bipolar, on medication, and still be super creative."
