A great young man of the 21st century, a highly educated and experienced otaku, inexplicably traveled through time while watching TV? !
Oh Mereddy Gaga!
Or an empty one? ! And being a servant to someone else? ! Why is it that when other people travel through time, their talents as generals and prime ministers dazzle the country, but when he travels back through time, he has to serve tea and water and is bullied? !
Hum hum hum! Don't underestimate the talents of the 21st century!
