We propose a fulfill program for short 8ks observations of 15 optically selectedTDEs at very late-times ($>>$ 1 year). This program will help us to (1)investigate the timescale of delayed X-ray brightening (2) probe the existenceand formation of a corona and test the efficiency of Comptonization atlate-times (3) measure the mass accretion rate which directly tracks the massfall-back rate at late times -- all at low cost and no scheduling constraints.
