Senaka-gurashi

A teenager named Meguru convinces his mother to let him live independently by renting a room for the summer. His mother agrees but installs a glass wall between his new space and the adjacent room, offering no privacy. His neighbor is a girl named Kana, who is the same age as him. The two have a poor first impression of each other, and the situation turns out to be very different from what Meguru had expected.
