"Everything I like must be excellent. I like it, so it must be excellent. I have no doubt about it." He and she reunited four years later; he and she are struggling to choose between friendship and love. Will he and she stay in the past or continue in the present? It is not a sadistic novel, it is light-hearted and funny, with a little bit of sadistic heart. It is narrated with reality as the main thread and memories as the background. It mainly expresses how the four protagonists maintain their original intention to treat work and love in this exaggerated real world. I hope readers will find it warm and comfortable, and I will feel at ease.
