2gether is based of a novel from the same author of Theory of Love, so I think it's not a sequel to this movie. <3
if you have a problem with age between the actors, just don't watch it. you're not being forced to lol.
i'm sorry for getting you wrong and assuming it was about the age. i don't have nothing against han ji min's acting, but i don't know the boy so i can't judge. i respect your opinion, but i hope they will do a good job. i really like the plot. :(
