"Mom, I am going to school".said yuuka. Looking out of the classroom, he saw something crash at the backside of the hill. After the class was over, he went to that spot. He saw a spaceship which was badly broken down. He heard a sound from the nearby bushes. When he turned, he saw a girl.her eyes are like the sapphires and her hair is like the sea. She is very beautiful and she is wounded and covered in blood. His heart is beating fast, some kind of unexplainable sadness is piercing his heart like a needle. He didn't wait for a second and took her to a hospital. The doctors are treating her. After some time, the doctors came out of the operation room and said she is safe. Yuuka sighed with relief. He took her to his room in his lab. Ai asked yuuka who is this girl. Yuuka told her to take care of this girl. Seeing the girl safe, yuuka is very happy. He stayed at the girl's side for the whole night. Next morning, the girl has woke up. She saw yuuka behind her and screamed "who are you?". Yuuka woke up and saw her waking up. He is very happy to see her getting up. He said "I saved you when you were collapsed with your injuries . I even took you to the hospital and took your spaceship to this lab. What is your name? Can you tell me?". The girl said,"my name is Lilly . thank you for saving me. I gotta go". Yuuka was reluctant to part ways with her. He said that her injuries will only get worse if she moved now. So she can take rest at his lab . He will provide necessary treatment to her. Lilly agreed . Yuuka was overjoyed and told that he will cook tonight for her. Lilly asked whether he can cook. Yuuka said that he can do all household chores. He tells Lilly to eat the food he cooked. Lilly tries it and tells that it's the best food she ever had!. Time passed and the two of them grew together. One day yuuka took her to his house and introduced her to his parents.
Both of them grew attached to Lilly as well. Dora asked yuuka about Lilly. Yuuka told him that he doesn't know about her but he completely trusts her. After some time when Lilly was alone in the room, yuuka visits her. But the thing he sawz he couldn't believe it. All the objects in the room are floating and Lilly is flying. Yuuka was in confusion.
"Just who is this Lilly ?"
