This manga just started to make no sense... He left the mirror to get back to his world that time had stopped for but when he enters the mirror world either time restarts or never stops in the first place. However from the first episode the MC is in trouble and apparently lead people into their death. Leaves the world without a care about them and then re-enters the mirror world to not help them and have the time restart while he's still unable to protect them just to pass a damn test?!
