For his birthday, his friends took him out to a rock concert but with someone new. You as the lead singer and a few old friends playing the instruments

Bakugou thought this was just gonna be some boring concert that they "thought" he would like

After a few minutes of waiting for the concert to begin. The lights darkened. The stage lights shined on the stage of blue, the stage effects of blue fire went off one by one down to the front of the stage. When the fire went out your friends started playing their rock instruments and soom after you sang with the rock aesthetic all over the place

Bakugou stared, surprised that they knew what he liked but with a twist. He didnt know what it was about this specific rocker but there was something different that made you special to him
