the last episode of Boy For Rent aired today so I can officially say, without reservation, don't bother. Even for the more interesting of the two couples (who definitely did have chemistry the whole time but that's the most positive thing I can say), it's not worth the time.
Other ones that weren't worth the time (though I've definitely mentioned before) Takane to Hana and Jao Sao Jum Yorm - both boring.
Also, not on your PTW but a CW that you've only just started, Theory of Love isn't completed yet but I am finding it less than compelling. There are only two episodes left so I will personally definitely finish it but honestly it's been so much skipping through episodes.
