How a live duel plays out
You don't chat and you don't type. You back one of the two girls, and the hearts you send are your vote. Both bars climb for the first forty seconds of a round, then lock — the higher bar wins that round, and the bars start from zero again for the next, so a girl who's behind early can still come back late.
Whoever sent the winning girl the most hearts over the whole duel gets her alone afterward in a private live. And backing the girl who loses isn't wasted: every heart you send also fills your own reward bar with her, unlocking her private content whether she wins the room or not.
Watching is free with an account; voting takes hearts. The clips above are short previews — the duels themselves run live.
