I dropped both Love 020 and Boss and Me, so we might have similar tastes.
Definitely watch Accidentally in Love! It's so fluffy, cute, and funny! It is "hate to love" and the couple bickers all the time, they are so cute! Great chemistry, amazing music, and best of all, the pacing of the relationship is perfect! With Boss and Me and other Chinese dramas, I find that the main couple get together way too quickly for my taste and that they don't show enough scenes in the relationship for it to be believable. But this one is perfect! The acting is really good as well. I can't recommend this one enough. :)
