While captured in 2007 at Pusan National University, Busan, South Korea, I recognized its botanical family, as Asteraceae by its leaf structure and floral biology. It is some kind of marigold, but no one could confirm the name of flower then.
The picture has been stored in my hard disk, and recently came to the surface while I was looking for some old photos of my elder kid. Now, with the help of Google Lens, ID of plant is confirmed. Its indeed a marigold!
