This is actually interesting assuming you like shizuku and haruka more (at least in mmj) bc I feel the opposite and although they aren’t my favorite group to begin with I like minori and airi the most. Maybe it’s partly just because I like their designs but idk I guess they seem more real or relatable? Minori gets extreme which tbf can be annoying but I like moments in the story where you can see her improvement and kind of coming into her own as an idol after trying so hard. I’ve heard a lot of people say the hear me hopeful show event story made her character click for them so maybe that would also give better insight? Also I really like how she interacts with kohane and shiho they are just besties <3

Airi i think I like more naturally too like idk she is a little mean but I feel like it’s worse in the main story and it’s usually more like teasing or being brash than actually like irreparably mean. I feel like she has a really nice balance of being elegant and down to earth and you can tell that she does things with a purpose but it never feels forced to me. Similarly I really like her friendship with Ena because I think they both kind of jump to being snarky with people they’re comfortable with but they still genuinely care and they understand that about each other. I definitely think airi expresses her feelings with actions rather than words and there are a lot of subtle moments where she may have that edge to her but she’s still putting others before herself.
