Rindou starts the drone after repairing it by the hardworking from himself for almost 2 whole weeks. Kira; his cousin, childhood best friend and love at first sight, is in middle school and has depression. She told no one about the pressure she had on her mind, not even the sweetheart cousin Ran, Rindou's older brother. Rindou and Kira's bond was unbreakable, mostly full of chaos and comedy. Kira threw the drone she made after 2 months hardwork after all she got from other was: "what an impracticable design" "won't be able to fly" "oh you, always making such trash" so, in disappointment, she threw it in the trashcan with teary eyes and he saw that. The pressure wasn't from these things, but alot behind that only Rindou knew but never confronted it infront of her as it would get really awkward against their regular conversations. Rindou proceeds to see the view in the camera that the drone was capturing, then flies it into her window. Thinking: "how happy Kira will be to see this!" and sees the vision in the camera, .....it showed Kira hanging from a rope, smth written on the wall: "I quit". As soon as he saw that, his love of the life, his reason to live; dying? He was filled with terror and sprinted to her room. He slammed the door open and saw that it wasn't too late. Her heart was still beating. He found a way and saved Kira "H-have you gone mad or something?!" he instantly embraced her with love and care with a hint anger plus relief. He rubs her back and keeps her close to his chest but earns no response from Kira, who just sat there like a dead living. His Kira... was not like this! She was bubbly, cute and funny!
