A quick description of the manga from a reviewer.
In the time-switch series “Ashita, Kimi ni Aetara” everyone’s breasts are absurdly out of proportion to their bodies and clothes and it’s almost hard to like the protagonist as she tries to fake her way through a day, until it becomes too much for her and she – quite naturally – breaks down in horror at having no idea what is going on.
I seriously don't get it, hope it will less confused in next chapter.
