This feels like it was written by an author who went crazy trying to lose weight!
Female lead: Gu Jinzhao is 172 cm tall and weighs 125 jin. She’s tall and striking, with a remarkably changeable personality: sometimes sweet and charming, sometimes noble and aloof. She comes from an extremely powerful family and has a wonderful home life. Her condition is a pathological obsession with losing weight.
Male lead: Jing Yuan is 185 cm tall and weighs 150 jin. He’s a formidable self-made man. Before meeting the female lead, he was the usual arrogant, untouchable CEO you see in novels. He hides his condition and weaknesses, so his arrogance is just a facade. After meeting her, he becomes an insecure, sensitive, suspicious puppy with a few schemes of his own. His condition is a pathological fear of getting thinner.
The two will get together, break up, and eventually reunite.
One-on-one romance, both leads are virgins, angsty romance.
