The two lovebirds are immersed in their own world, making love to each other every day before and after school, as if to confirm their love for each other. They can only see themselves at all times, and their minds are full of each other. They always deepen their love in secret, in places where no one is around and no one can find them. Their tongues entwine as if to confirm each other's feelings, making their crotches hot and wet. "Let's stay together forever (heart)."
