She fell in love with Kudo Shinichi when she first met Sakura Kudo when she was a child.
Like Mao Lilan, she has known Kudo Shinichi since she was a child.
But why, everyone only likes Mao Lilan, who is Kudo Shinichi's childhood sweetheart
Later
She slowly moved away from Kudo
She finally gave up until Kudo turned into Conan and disappeared.
Sent a letter
"Kudo Shinichi, I decided not to like you anymore."
Kudo was very happy and sad after reading the letter
Because he also likes the other person
He won't let them miss each other
Intention: I like you, it's always been you
