Forgotten Title transmigrated into a world where everyone else get systems in their school year except MC

Some details(I have only read one or two chapters of it actually):

In the modern parallel world, MC get's transmigrated into a world that is similar but here everyone will be getting a system.

In this world, no one can actually see what the other's system is unless they infer or someone says it outright. MC has no system I think, but he is able to see what system others have and their functionalities.

The MC get's transmigrated and the moment he comes to, he realises that he is writing a test and one of the questions was what happens if other's get to know about your system? and so he writes the answer as "Then we won't be able to show off anymore"
