Zhang Hao, the second son of the top wealthy Zhang Group, has lived under the shadow of "eldest son inheritance" since childhood - his father regards him as a "superfluous candidate", and his mother's attention always tends to the outstanding eldest brother first. Even at family gatherings, he is the most easily ignored existence. In order to escape from his suffocating family, he concealed his identity and opened a small photography studio in the city, using his lens to capture the fireworks of the world and hiding his loneliness.
Until he met Su Wan, an ordinary girl who worked odd jobs in a gallery and was a part-time illustrator. She is carefree and will argue with clients over a painting. She will also give up her umbrella to stray cats on rainy days. The light in her eyes just shines into the corner of Zhang Hao that has never been warmed. The two met because of a misunderstanding about "taking the wrong photo". From teasing each other to healing each other, Zhang Hao gradually found himself, and Su Wan also strengthened his artistic dream.
But when Zhang Hao's identity was exposed, the Zhang family's opposition came as expected: his father forced him to marry a well-matched daughter by severing the relationship, and the eldest brother regarded Su Wan as a thorn in Zhang Hao's side who "impeded Zhang Hao's ability to live a peaceful life." Even his mother, who had been gentle to him, advised him to "recognize the reality." On one side was the light that he had finally caught, and on the other was his blood-connected but cold family. Zhang Hao chose to resist for the first time - what he wanted was never the inheritance of the family, but to live the way he wanted with Su Wan in the starlight of the floating city.
