Does anyone know the song that Shenmu sang in the school choir in Short Love?

I recently watched the Japanese drama "Stubborn Love". In the first episode, Shenmu Ryunosuke played a song sung by Sapporo at school, which was also sung at the end of the first episode. The whole family was singing at dinner. The tune is exactly the same as the fireworks in Gao Yaotai.

People who love spring and have beautiful hearts bloom like all Qiu Jin, my friend. .........
