I Come From Humble Beginnings

After meeting Alice Yabusame in a burger shop, you and your friend Shin Tsukimi decide to join his and his sister's, Reko Yabusame's, band, Halestorm.

The guy who just can't seem to leave Shin alone, Sou Hiyori, is now bothering all four of you. But this time, he won't be shaken off so easily.
