The two met in front of a pomegranate tree with vermilion flowers in the hospital's courtyard. Suzuno, who works at the hospital, meets Ryu, a high school student who comes to the hospital for rehabilitation. If they hadn't met, they wouldn't have hurt each other. But they probably wouldn't have been able to fall in love with each other. Suzuno is the eldest daughter of a large family with six younger siblings. It sounds nice to say they have a large family, but this is the result of her parents repeatedly making up after every big fight, and by doing so, the couple seems to have been stretching out their love in a twisted way. The proof of this is that her mother eventually became emotionally exhausted and left her husband and seven children behind. From then on, Suzuno became a mother figure to her siblings, and even now that they are all married, she continues to live a life of devotion to others. Even though she was told that it was time to think about her own happiness, Suzuno, who had seen her parents longer than any of her siblings, could never have imagined the happiness that would come from finding a boyfriend, getting married, and having children like everyone else. However, Suzuno's outlook on life was greatly changed when she met Ryuu. Suzuno was put in charge of Ryuu's rehabilitation, and felt a sense of comfort from his bright smile and affection, as if she were dealing with her younger brother. Then, one day, she heard Ryuu talk about the emotional distance between him and his family, and felt a painful sense of empathy. Then, after feeling something she shouldn't have, Suzuno began to feel something that she should not have, and as the days of rehabilitation passed, her feelings grew bigger. The relationship they were meeting under the pretext of rehabilitation, the illusion that arises in a certain environment, the age difference between them... She told herself many reasons and put a lid on these feelings. She thought she should put a lid on them. --I shouldn't fall in love...!
