It's a cycle. Jinhwan had always been open in his interviews about his sensitive personality and his moodswings. So finding himself trying to be, alone is something common, "trying" because Hanbin is always there along as the cigar in Jinhwan's hand. And thats is not a good combination, not when Hanbin's curiosity for smoking is growing more and more, and Jinhwan, this time, doesn't have enough energy to go against it.
