A cheerful and playful "fat elf", a snarky "venomous tongue", and two strangers who are incompatible with each other. Due to a strange combination of circumstances, a fierce "spark" was created due to an off-line medical examination - of course it was not a happy spark~~~. After the physical examination, the "Fat Elf" remembered the "Vicious Tongue" severely. As long as they meet, there will often be scenes like this... The happy Pang Pang and the arrogant Tsundere have gradually developed some different feelings, and the campus life of the two big babies is becoming more and more interesting.
