I don't vouch for quality, since that's totally subjective all I can really say is that I really enjoy this, but when I'm down, I like to read W-Juliet by Emura. It's a fluffy true love conquers all problems (and so does hard work!) manga about a boy who dresses as a girl (for plot reasons) and a girl that people mistake for a boy who fall in love and want to be actors. It's cute, silly, and even when things are terrible, they all work out for the best within a couple of chapters at most.
