Tidal Love numbers provide us a handle to test the nature of compact objects, as well as theories of gravity. There have been several clarifications recently, which makes our understanding of these Love numbers better. I plan to discuss these recent developments. I will show that the tidal Love numbers of a non-rotating black hole identically vanishes in the static case, which is not true in the dynamical scenario. While for rotating black holes the situation is a bit more involved. Besides, I will also discuss fermionic perturbations leading to non-zero static Love numbers for black holes. I will also highlight some remarkable novel features, for ultra-compact objects as well as for quantum BHs.
