Every Saturday and weekend, the library is always extremely noisy. Su Ping suppressed his irritability and watched boring course videos while secretly complaining about the sources of strange noises around him. The eye-catching jingling of a bunch of bells broke Su Ping's last bit of patience. She turned her head to look for the source of the noise. It was at this time that Yu Yang almost jumped into Su Ping's life where she could see her old age at a glance. I think Su Ping never thought that this little girl with single eyelids and baby fat would leave such a knife-like mark on her for the rest of her life in the next few decades.
