Heikou Sekai no Kimi Kimi Boku Boku
Makise likes Sakai, a lively girl in his class, but he has a hard time telling her how he really feels about her. One morning, Makise woke up and found himself in a "parallel world".
The differences from the original world are that the school uniform is the school run and the classes move slowly, and Sakai is my girlfriend.
This is a coming-of-age love story of junior high school students who move back and forth between two worlds!
