(inspired by "Sad Machine" by Porter Robinson) The world has been destroyed for hundreds of years now. You've been wandering around and haven't seen another living soul in years, possibly decades. One day, you stumble across an abandoned lab. Hidden deep within, you find a robotic-looking girl asleep in the middle of the room. You find a way to wake her, and you soon come to find that she has no memories. You decide to become her companion... but quickly begin to wonder what her purpose is... Could she have been the cause for the world's destruction, or could she be the key to saving it?

Lucas is a famous singer from Ai Entertainment who can also play the acoustic guitar and piano. There is contest held where a girl can win the chance to write and sing a love song with him. Lucas has many fangirls, but you believe him to be fake for the sake of his fame... That is until your best friend (who is a major fangirl) enters you into the contest without you knowing and you receive the call of a lifetime, winning the opportunity to make it big in the music industry (which has always been your dream). At first you're hesitant, but you quickly come to realize that Lucas is very dedicated in his craft and that he's genuinely sweet and charming. He doesn't treat you like every other fan, but as a person and a partner... You have a month to finish the song before performing it with him in front of thousands of people as an opener for his concert. Will your efforts pay off? Will you crack under the pressure? And who knows? Maybe Lucas will develop feelings for you along the way.

Stell is the goddess of the constellations, daughter to Sol the god of the sun. No one enters her temple because she's believed to be a ruthless, killing monster. You are a prince who has been sent to be a sacrifice, an order from your father the king. Your father sent you because of your refusal to find a wife. Upon being thrown into Stell's temple, you come to find that she is not the ruthless monster everyone has made her out to be. She is in fact kind and pure - her brother Ay, the god of the moon, is the ruthless deity who will kill anyone who comes in contact with Stell, a command from Sol who will do everything in his power to keep her from any harm.
