In this teen sci-fi drama, you play the part of the Sun. And you are in love with Earth Chan. You two are in avatar-like forms and making the most of your days together. You confess your love for her and how she is your favorite planet and you desire her. Looks like the feeling is mutual. This game has dialogue and is beautifully drawn. You the Sun and her have a romantic interlude where she goes down on you and make love to her over and over again. It's a love story and the lessons bout the planets are nice!
