Is Perfect World coming back?

Architect Ayukawa Itsuki is paralyzed from waist down. Although he was the ace of the basketball team back in high school, he injured his spinal cord in an accident while in the third year in university. After that, he decided that he would not play basketball or fall in love ever again because he is wheelchair-bound. Itsuki was Kawana Tsugumi's classmate and her first love. Tsugumi liked drawing and her ambition was to get into art college. But she lacked confidence and gave up on the exam. Even though she got into an interior design firm, it is a clerical position. Itsuki and Tsugumi happen to meet again at a work-related drinking session. The two of them are attracted to each other. However, they face problems including disapproving parents, the appearance of a love rival and illness as they search for the meaning of happiness.
