Hi My Sweetheart is a Taiwanese Drama starring Rainie Yang and Show Luo. I finally finished the last ep today and I must admit I was decently surprised being the first twDrama that I’ve watched. I have never cared about Taiwanese actors or actresses at all before, but I guess Rainie and Show earned a bit of my respect for showing good acting skills 
Synopsis (taken from DramaWiki):
Xue Hai was a certifiable dork when he first arrived in Shanghai. After his schoolmate Bao Zhu saved him from bullying, she became his first love. Then, a misunderstanding caused them to lose contact when she moved back to Taiwan. He thought she dumped him. So he transformed himself from a dork to a hunk in order to seek revenge.
For those that understand taiwanese, you can just watch the whole drama on youtube. I myself can understand a few words here and there, but that’s pretty useless since I can’t understand the whole idea lol, but I think I already learned quite a bit from one drama. So for those that don’t really understand like me, thankfully Still-Frames subbing group is subbing this drama. Thanks alot! There are megaupload/torrent links on their site.
Have fun watching! Now, I gotta get back to studying
