Based on the 2013 Japanese version of "One Kiss", the character's psychology is restored and the plot direction is sorted out.
[Summary of content]:
Except for the loss of her mother when she was young, Kotoko Aihara's life had no twists and turns. As a result, his favorable impression of classmate Naoki Irie at the high school entrance ceremony was as shocking as being hit by a meteor, and because he had no way of confessing his feelings, it lasted for two years.
Because relying on intuition is not enough to appease the inner excitement, or perhaps because of the naive fear of missing out on the opportunity of love, and because she is about to graduate, the increasingly overwhelmed Kotoko-san does something that exceeds her ability. She stayed up late and looked up the dictionary, and wrote an extremely sincere and heartfelt love letter to classmate Irie. She went to the campus gate to block him early the next morning, looking forward to sharing her excitement with him.
