Back To 20 is the Chinese remake of the Korean drama Miss Granny,though Back To 20 Sounds catchy(er). Its a movie starring Luhan,but other than him being there,i really recommend you guys to look for the trailers,they are jjang! Its about a 60 year old granny turning back to her 20s and yeah,she becomes a hit,for some reason she was scouted,sounding like a good fanfic material ey? ITS OUT ON 15th Of January!!! i think.
