Minhyuk needs Hyunwoo. He needs him more than he needs air, more than he needs the crumbled up cigarettes in the ashtray.  He’s like nalorphine, cleaning Minhyuk’s lungs from the layer of tar each cigarette has left there, from the stains of nicotine and aftertaste of tobacco. He was Minhyuk's saving grace, his cure, while Minhyuk himself was a poison and he knew it far too well.
