Serizawa Kokone

A spoiled little sister who has always had honest feelings for me

When they met on the way to school in the morning, Kokone's lonely eyes left a strong impression on Kazuhiro. However, as they gradually became more comfortable with each other, her true, slightly childish, innocent and pure brightness began to emerge. Kokone clings to Kazuhiro and calls him "Big Brother". Even so, it can be sensed that she is careful not to cause him any trouble. Having lost her parents at an early age, she was raised by her grandparents. Despite her appearance, she is surprisingly strong-minded, which is probably due to her good upbringing. One morning after they met, Kokone hands Kazuhiro a boy's doll. What was she thinking at that moment.
