Beng Tie: What Do You Mean There's Another One?

This book is also called Them from the if line (multiple heroines) (Yandere?) (Lily) Star Railway. It is very slow-moving. The emotional line is in the middle of each if line. If you want to watch the love part, it will take a while. The above is a summary of the plot. If you don't mind, don't read it. —————— "Take it, this is the last wave!" The self from the if line seems to have left some treasures for Auleus. When she was forced to wear a ring by a weird black tower doll, some if line memories came to her. Every time, it was a different self... But why did she have to repay the love debts of other lines of selves? Oleus, who had just received the memory and was still in a daze, was pulled into his arms by the black tower doll. While the doll comforted her with words and told her thoughts, it looked at her with a dangerous look, as if it wanted to eat her up.
