I just finished watching the drama Kurosaki Kun No Iinari Ni Nante Naranai and I waned to watch something similar, where the main characters have a tsundere type of relationship.

Has to be japanese drama or movie but not too old, has to be released after the year 2007 atleast..

All recommendations welcome =D TY in advance.

what does tsundere mean? I saw comments on Ryu Jeon Yul about it they were like RJY is trundere
Go to YouTube and search 'tsundere SNL' (I don't know if I'm allow to link directly), Taemin demonstrates tsundere very well, it's funny :) 
@94lovekdrama: "Tsundere is a Japanese term for a character development process that describes a person who is initially cold and even hostile towards another person before gradually showing a warmer side over time." Lol.
thaaaaaaaaaaaank you! :) <3 
then maybe Tomorrow's cantabile - Joo Won  could be
