In 2009, Rick Astley released a song under the name "Never Gonna Give You Up". In this classic hit worldwide beloved single, the lyrics "We've known each other for so long your heart's been aching, but You're too shy to say it" are present. What can be interpreted the artist is trying to say from these lyrics?
The artist might be trying to convey that the subject of the song has been in love with the singer for a while now but the subject is too shy to admit it. Hope this helps! :)
