The opening theme for the TV anime "Ganbare! Nakamura-kun!!" based on the Harudei original work has been decided as the collaboration song "Sudantan te Koisyo" by Yasuyuki Okamura and Kento Nakajima. The main PV using the same song has been released.
"Ganbare! Nakamura-kun!!" is a BL comedy about a shy high school boy, Okuto Nakamura, who goes wild and delusions surrounding his unrequited love. ``The collaboration on ``Let's fall in love instantly'' came about after Okamura made an offer to Nakajima. In addition to writing, composing, and arranging the song, Okamura also participates as a vocalist. Okamura introduced the song, looking back on his time co-starring with Nakajima at ``MUSIC AWARDS JAPAN 2025'' and saying, ``It feels like a melody I heard in a dream and an encounter in real life are connected later on.This work was born out of that kind of coincidence.'' Nakajima commented, ``The demo I received had a melody that made me want to dance, reminding me of Mr. Okamura's lighthearted performance when I saw him on a music program, and I really enjoyed recording it.'' Along with the release of the song, artist visuals and distribution jackets drawn by Harudo of Okamura and Nakajima were also released.
The TV anime will be broadcast from April 1st. Chiaki Kobayashi will play the role of Okuto Nakamura, and Yu Sakakibara will play the role of Aki Hirose.
