I Seem to Be Missing Something from You

He saw a circle of friends in which two people showed their hearts. He is not one of them. From that night on, he relived his past all over again. It's not a recollection, it's a real walk-over - he has re-taken every fork in the road he has taken since high school in his mind. Help C chase B. Chase B yourself. I and B are really together, but they have turned each other into strangers in the marriage. Repeatedly returning to a person whose name was never mentioned, trying to save her, only to discover that she did not need his saving. He walked all possible roads and found that at the end of each road was the same door. Inside the door was an old monk sweeping ginkgo trees, sitting on a futon with two cups of tea in front of him. One cup was for him, and the other cup was for whom he had forgotten. This is a book about "not finding yourself in love". By the time he found out, the drinks could no longer be handed out, the tea had been changed many times, and the dead branches had been watered for many years. Some people came, some left, and some were always there. He never looked back.
