Fans were frustrated.
Recently, Mark Lee made a post on Instagram and Weverse that stirred up much controversy online.
While the photos themselves were fine, his song choice garnered much attention.

He used IU’s “Bye, Summer,” which is a well-known fan song. He also posted a fan-made video that used this song in a Weverse post.

However, this garnered a negative response from IU fans.
생일해시에 아이유 가사 인용한건 걍 넘어갔는데 왜 자기들끼리 아이유 팬송으로 서사 만들어서 부둥켜안고 엉엉 우는거지 덕질을 신기하게 하네 pic.twitter.com/o14uX12rKh

I let it go when they used part of IU’s lyrics for his birthday hashtag, but I cannot understand why they are using IU’s fan song for their own narrative and crying over it.
왜 남의 팬송을 본인들 서사 쌓는데 이용하시는 건가요??

Why are you using someone else’s fan song to create your own narrative?

The comments left under the song on Melon are so ridiculous. Just f*ck off. Your Mark has gone off to be with Jesus.
