A young girl, Tsukie Chishima, was bullied at school and suffered brain damage and lost some memories. She had forgotten the hero she had longed for in the beginning, but she still did not give up looking for this person. In order to save the depressed Tsukie, her parents sent her to Chiba Mihashi's house, the home of her only friend and cousin Mihashi Takashi.
And the day before she came, she unexpectedly met Tomoji who was covered in blood? That boss who bullies the weak and fears the strong? She deeply disliked and misunderstood him, but he saved her from danger time and time again. She felt like he wasn't that bad.
Her memory was finally awakened. It turned out that the boy who protected her in junior high school was Tomoji Katagiri? Realizing that she had misunderstood Tomoji, she felt extremely guilty, and changed from a shy girl to a gummy girl. She vowed that she must become the female supporter of Kaijiu Boss.
Tomoji: "What the hell are you doing?"
Yue Hui: "Fuck you."
Chiji: "..."
Tomoji Katagiri, you will never get rid of the shameless Tsukiji Chishima in your life.
