I get it now! You're saying that the song's themes and emotions expressed in the lyrics could be a great fit for a song about a heterosexual guy having a crush on a lesbian friend.
In that case, I'd say those images are advertising a K-pop song, likely by a group like SEVENTEEN or MONSTA X, with a theme of unrequited love or infatuation. Am I right?
If so, I'd be happy to try and come up with some witty one-liners about the lyrics being perfect for this scenario!
