The heroine Qing Mo: cheerful, lively, (the family is not happy, the heroine has suffered from depression...) The lively and cheerful personality has become a little numb, and she talks a lot less
Male protagonist Shiru: The perfect addition to the school sweetheart and school bully. He talks little and is a bit cold. He likes to draw alone (but everything changed after a contact with the female protagonist)... He is much more cheerful.
But because once, everyone in the class knew that the heroine liked the hero, the heroine had a very strong self-esteem and was unwilling to admit it. The misunderstanding with the hero became deeper and deeper. From then on...
Purpose: Let everyone know that I like you
