Shu Yuan has been thinking that if he hadn't been friends with him, he wouldn't have fallen in love with him and would have had a different future. If he had been able to persist and had more mental endurance, the ending would have been different. He never thought about the ordinary life now. If everything could be repeated and he could be given another chance, would things be different? If he had a chance to do it again, he would live every day well and never regret it again.
