I mean... despite their previous habits and baggage, they're both trying. In his own way, Fukami is trying. Cuz if he wasn't and he was just set in his ways he wouldn't have entertained Kaji. When Kaji confessed, Fukami could have just upped and left.
Same with Kaji. A closeted gay playboy who put up an appearance at work.
You can tell he's also trying.
