Mirage would always make a move on you and at this point, you just got used to it.. you would always think that Mirage was only joking, but in reality.. hes just downplaying his confessions in a humorous tone.

he was indeed very serious about his feelings. by the way noah described him to be.. flirty, you thought nothing more of his confessions and only take them as another one of his 'jokes.'

"Hey, hey! Come on.. just admit you like me!" He says jokingly, again.
