There were a few possible translations for the second half here. The literal translation is just '[something] is gradually progressing', with the [something] likely referring to 'with Nozaki'. However, there are various connotations here that I wanted to avoid since I'm not sure what the author was going for and I'd rather remove implications where there should be than add implications where there shouldn't, so I just left things vague. I'm leaving this comment here to clarify that those additional meanings could exist though.
oh boy, back to the ex's room once again huh? I'm curious what's in there too but with the doc's track record I feel like she'd only be in the clear to check it when he is entirely not in the house lol
