Omg actually you are so right. I think this is the first I've seen a bl cover with this much symbolism.
The way Cheol is embracing Minyoung while also hiding him using his body, while his wide eyes and wary face is staring back at us. It really represents his relationship with Minyoung: that he really wants Minyoung but he's his big secret that he needs to hide.
Then you got Minyoung embracing Cheol not only with his arms but also his legs, fully representing his possessiveness to Cheol. Not only that but he seems likes he's naked, pair that with the way his eyes looks threatening, they fully represent his shamelessness or perhaps fearlessness. That he doesn't care for anyone except Cheol.
Damn, u both r so amazing! I APPLAUSE ヾ(☆▽☆)
I live for analysis like these
I think I just realized why the cover is like that. Cheol is looking back at us, in fear that we will find out he is gay. And minyoung is being his generally possessive self.
And the snake is coiled around the flowers to symbolize Cheol will never be free of minyoung.
