I Am Reborn and Just Want to Be Single

Gu Yicheng, a 35-year-old high school mathematics teacher, was distracted by a phone call from his parents urging him to get married and had an accident. He was reborn on the day he graduated from high school. Since God has given him a chance to be reborn, he should cherish this opportunity, especially not to leave any emotional regrets in this life. How should I choose between the tsundere and sweet Bai Yueguang and the ordinary and gentle treasure girl I have known for four years? "Both of them are good girls, what should I do if they don't want to give up? Forget it, just be selfless and take them all at once!"
