ok so i have a problem: i got 6 hearts, all purple, and when i try to get 15th washroom event (HJ), it doesn't happen;

what i do: i go to bath alone, wait & peep, and then just constantly look through panties. then after a few times it for some reason sends the text of lick lick scene, the girl is standing nearby talking about milk, and then her hair disappear and she appears behind the door and runs away;

am i doing something wrong?
