Help finding a drama

Seems like the title is 梦中犹是少年游. I'm trying to find ML's name through FL's mdl actor page but there's none for now.

Btw, that vertical drama is pretty good.

Found a link to the novel too, if maybe you'd like to read the novel. (Just hit the translate button on chrome/use google translate)
