SO KAWAII! Harumi really likes you and loves to make the other girls jealous, Its your job as senpai to help her do that by choosing her each time she shows her pretty little face.
you only get once chance to show harumi how devoted you are to her and if you tap another girl then she will let you know you made a mistake.
it gets harder as you play as the more you keep choosing harumi, the faster the other girls appear so you gotta be quick to please cute harumi.
use your speed, reaction and super senpai powers to win harumis heart (and get a high score of course). Good luck and god speed, Harumi is waiting for you ;)
