All I did was ask my twitter friends, "what is that game with the anime girl cards?" and then I fell into idol hell.
Eli is best girl, NozoEli is OTP - it's perfect.
But I have soft spots for KotoUmi and NicoMaki...and then MakiPana and EliUmi and EliMaki...and my rarepair is EliPana. For Aqours, Yoshiko and Kanan are best, and OTPs are YohaRiko and KanaDiaMari.
Started playing in 2015 - August on EN, October on JP.
I stream speedruns on my twitch channel - come take a look.
Other mobile games I play: Puzzle & Dragons, Granblue Fantasy, BanG Dream Girls Band Party, Fire Emblem Heroes, Merge Dragons, Fate Grand Order
