  MP Gem has long been suspected as a long-period eclipsing binary, which had
not been seen in faint state for 71 years since the discovery in 1944. Its
nature has been a mystery. Using Public Data Release of Zwicky Transient
Facility observations, I finally reached a conclusion that this object is a VY
Scl-type cataclysmic variable by the detection of the deep faint state and the
rising phase in 2018.
