The opening “Natsu ni Kasanete” is performed by Dialogue+, while the new ending “Tilt” is by harmoe. The second trailer and visual offer a closer look at the characters and the central reunion between Hayato and Haruki, which drives the entire story.

Oh Boy, Was I Wrong About Her is a light novel by Yu Hibari with illustrations by Siso, starting on Shosetsuka ni Naro in 2020 and published by Kadokawa since 2021. The manga adaptation by Oyama runs in Comic Walker since the same year.

Does the seven-year identity misunderstanding twist seem like a fresh hook to stand out among this summer’s school romances?
