The search results confirm that沈震軒 (Shen Zhenxuan) indeed collaborated with his girlfriend 陳欣妍 (Chen Xinyan) on the MV for his new song “最幸運的平凡人”. The articles explicitly state that Chen Xinyan is the female lead in the MV and that their intimate scenes required no acting guidance because they were simply “doing their daily routines”. The song is described as a warm love song that Shen Zhenxuan wants to dedicate to Chen Xinyan and others he is thankful for, reflecting his journey and appreciation for his steadfast partner. The MV also includes snippets from a short drama and features guest appearances from celebrity friends. One search result mentions Chen Xinyan discussing a failed proposal attempt by Shen Zhenxuan on Valentine’s Day in the past, indicating their relationship has been public for some time and that marriage has been a topic of discussion. Another result from 2020 mentions Chen Xinyan finding Shen Zhenxuan boring, which provides a contrasting historical perspective to their current public display of affection in the MV.
I have gathered enough information to construct a detailed analysis and report as requested, covering the collaboration, the naturalness of their on-screen intimacy, the song’s dedication, the MV’s additional elements, and the public perception of their relationship over time. I can now proceed to synthesize this information into the required format and length.
