Singer Eru revealed that B2ST unknowingly rejected one of his songs.

On the August 25th broadcast of SBS Radio Power FM's 'Jung Sun Hee's A Night Like Tonight', Eru discussed his new mini-album 'Feel Brand New Pt. 2', which includes "I Hate You" featuring B2ST's Junhyung.

Eru stated, "I want to give B2ST a song I composed," and DJ Jung Sun Hee asked, "When do you think you'll be able to achieve that dream?"

The singer then revealed, "To be honest, I gifted B2ST a song. I gave a song to B2ST's manager who I'm close to, and I didn't hear anything back even though it'd been a week. I was busy producing, but when B2ST made their comeback, I realized I had been rejected. When Junhyung came to feature in my title track, I asked him if [the song] was that bad, and he said he didn't know anything about it. So, I just threw that song away."
