Being in a relationship with both of them is, surprisingly, pretty laid back. Not only because they won't force you to do something you don't want to, but also because it's very unlikely that you'll have something to argue or even fight about; most things are usually talked about, especially after you find yourself comfortable enough to talk to them about your feelings.
That being said, Aoi was the one who fell first — she is always sharing everything to the both of you, and loves to spend time with both of you, not only because she gets to unwind, but also because she claims spending time like this brings inspiration to her songs. And, between only the three of you, she likes the songs she writes more when she's with you.
Tsubaki was in the more complicated end — she has many feelings herself, don't get it wrong, but it is difficult for her to express them. Many times she finds herself jealous of you, but after you came along, she started feeling jealous of Aoi too. Above everything else, though, she wants so deeply to try and show you that she cares and loves the both of you. The best way that she's able to do it without feeling overwhelmed, is being able to sing for the both of you… And she hopes you enjoy her singing too.
I think it's safe to say that you shouldn't expect much of a pda from both of them; Aoi won't start anything, as she's afraid of making you uncomfortable, and it's oh so easy to make Tsubaki embarrassed, she probably won't start anything herself. So, if you want anything as simple as walking hand in hand with any of them…. It's up to you to do something. (Sorry)
Expect the most comfortable dates, though! Despite the fact that they probably ask Hiiro for advice, the places they'd take you would be some comfortable places that wouldn't overwhelm either of you. Going out with them, especially when it's one of them choosing a place to go, is a guaranteed good time.
Besides that, however, expect being invited to every RONDO show. Not as a mere crowd member, though — you will be backstage with the four of them most of the time! Normally watching their shows in RONDO's cabin, and being greeted with chaste kisses the moment they finish their lives, it's the way that they find to make sure you know how much they love you.
Talking about RONDO, expect being teased by both Hiiro and Nagisa. They will be making questions all the time about the three of you (especially when the other two are around) just so they can see one (or all) of you getting embarrassed. Outside of that, however, it's highly likely you'll have a good relationship with both of them, given the fact that they're pretty easygoing.
Just know that your input and opinions about their performances are indispensable! Before making a show, finishing a song or choosing a place to perform, they will always make sure that you have your opinion on it — not only because you are in a relationship with them, but also because you, as a fan, can give them insights into things they don't usually think about when performing. After all, you can give a new point of view for them! The way you see and experience their music is very important to them, after all, is the best way they have to communicate their feelings for you.
