Ever since she was a child, Yuka has a well-groomed face and was often ridiculed by the boys in her class.She has a quiet personality, she just smiles silently without saying anything back.She kept her smile even when she was given heartless words, and she always remained a good person Yuka-chan.The turning point for her was when she entered high school.Yuka studied hard for the exam, but she fell ill just before the exam, and she only passed the school she received with a non-slip.For Yuuka, who believed that her efforts would be rewarded, the incident was so big that she denied her life up to that point.Her new classmate's sweet words enter her sulky mind.Gradually, she wore flashy make-up, her speech and behavior became crude, and she began to go out night after night on the streets despite her student status.Surrounded by her so-called delinquent friends, she seems to have a very happy and fulfilling life.However, every day is empty and doesn't actually produce anything.The words of her parents, who were worried about her, could only be thought of as annoying scoldings, and days continued when they hardly exchanged conversations even when they met at the dining table.One day, when Yuka and her friend were staying at the drink bar at the family restaurant for about three hours, she suddenly received a call from her mother.A call from her parent that she normally ignores.But for some reason, she answered the phone with a strange feeling of unease. "Father has fallen."Yuka is upset by the suddenness.But before she could think, her body moved.She grabs her bag and runs to the hospital.She entered the hospital room and what she saw was her father with many tubes attached.Seeing her mother break down in tears, Yuuka thought.She doesn't want to worry her parents anymore.From that day on, every day after school ended, I went to the hospital room.Every day she devotes herself to studying beside her father.As her father's health gradually improved, so did her grades.She no longer hangs out with her bad friends, and smiles more and more with her mother.A year later, her father was discharged from the hospital safely, and Yukamo passed the entrance exam to the university she wanted to go to.Yuka, who studied hard at university, is now an office worker at a medical equipment company.Her medical power that helped her father was also the power that rehabilitated Yuuka at the same time.Every day, Yuuka hopes that her work will help strangers and make them happy.
