(~Completed~) Crossing The Line AU Yu Hao was a famous volleyball player... key word, was. Until he took it a little too far and sustained a career-ending injury that broke his heart... and his ego. Taking the suggestion of his manager and former coach, Yu Hao joins calm-tempered volleyball and swim coach Zi Xuan, who contrasts to his hot-and-heavy personality. Through many fights, arguments, and pouring hearts out to one another, the two clashing souls find a peace together. But, will the "special friendship" last, or will it be spoiled by something uncontrollable?
