Dazai already craves it, but for all the wrong reasons. He wants to fuck Chuuya bc it'll feel familiar, like he's doing his job and doing it well again. But things have started changing since the aquarium. There are new feelings starting to swirl that he can't put a name to, but they're building the longer he and Chuuya are alone. I think soon we'll start to see that internal battle more clearly... thanks for asking <3 I could talk about overture all day long hehe
