Apparently, almost all of Bingwen's scenes were romantic ones considering his title being 'Romantic King' which was awarded to him by all the fans.
Todays' scene was where Bingwen confesses his love to his significant other. Nie Chenguang who plays the second female lead reciprocates his love and they share a kiss under rain.
This scene is supposed to be the most romantic one of the entire movie since the male lead was famous for his martial arts rather than romantic scenes.
He was said to be the only actor who never participated in any of the kissing scenes until now from the moment he joined this industry.
Hence today's scene was given too much importance by the crew and all the staff.
The settings for rain were ready which was definitely artificial, since there wouldn't be real rain when required.
The director explained the scene to all the actors and once everything was cleared, then everyone entered their roles in their given locations.
