Tbh i think they had used them at the same time or rather Rui used it first. Notice that Rui’s Maria came nameless, but Mashiro „is” with Rui.
Shady, but works
I think the same time is possible too but rui using it first is kind of confusing? Idk know why tho I mean look.....mashiro is some kind of young master but in the latest chapter it appears mashiro becomes just a normal commoner .. isn't that means that time already passed by? I think something happend about his household Then later on he met rui through poster
Ok I think maria is some kind of Tinder app/ Dating app which is technologically advanced but shady as fuck...
Mashiro is the first one who used maria right ? Then he will describe his preference what kind of robot he wants then boom! Rui showed up and there's the 3 month rule..... end..
Later on...Rui used it.....now here's the odd thing!.. rui describes what he preferred, a girl with a big boobs right? but despite that mashiro/ kuro is the one who showed up..
...it means that maria will "automatically" choose the previous owner of rui (robot) and maria will copy the face of that previous owner and make it a robot for the real Rui
but why would maria do that? That is why i think that maria is a dating app to satisfy the users demand, to find their pair and a lovelife
..its not a coincidence... but i think its already in the system
i mean its shady as fuck...it means maria is capable of copying information and the actual owner of that info
Ok about the rings...i think the ring that mashiro received is the copy of the original one it means the robot and the real rui have the same rings and the robot gave that ring to mashiro thats why it has a same design ..maria is capable of copying the exact same thing right
But dude? If maria was never introduced to rui then he would never meet kuro? Thats the point here ....i think they are fated to meet again not a coincidence... (≧∀≦)
