The primary thing you need to do is focus on the Fortune Social Link. Progressing far enough in that unlocks a reading that'll bump up your relationship with any confidant without costing time. Basically mandatory if you wanna max them in one playthrough Also to answer the question in the title, yes. This is in fact a P5 Forum even if it doesn't look that way sometimes

Ah. Thank you. I recieved similar advice on another forum, but having this confirmed makes it a lot easier to plan on who to hang out with. It helps that I've been working with Chihaya (fortune) for a bit now. Almost at rank 5, and I believe that comes at rank 7 or 8. I will keep working then. I presume this works with all the confidants (lovers, temper, sun, star, etc)?

Yeah, you can do a reading with all confidants, but some of them (like Sun) have time gates where they won’t progress if you’re too early, and if you miss the window you won’t be able to get them anymore

Sad to say Chihaya (Fortune) and having a persona of the same confidant you're trying to raise are the only real ways to boost the ranks. Granted, you also need to say the right things to start getting the x3 booster during the scenes as well.

I managed to Max all but Devil first time, which I didn't even start because I wasn't really interested at the time. Can confirm as well, Fortune is a massive time saver. Don't hang out with someone who you won't get a rank up for, too.
