First off, it's for sure not the best, but it's definitely not the worst.
My personal gripes with the series are with the first one or two episodes.
The nerdy persona the mc has is definitely a personality you're gonna need to bear with.
Also, the stepping-stone persona can be off putting, untill the bonds become more developed.
The supporting cast is what carries the series for me,
but after you get through the first episode, i'm sure your opinions will change for the better.
The plot doesn't seem to go anywhere major,
its mainly about the vending machine finatic helping out the supporting mc girl.
