Anyway, I'm Falling In Love With You. manga volume 3 features story and art by Haruka Mitsui.

Watching fireworks lighting up the summer sky is Mizuho's ultimate vision of romance. Who is the lucky guy to share that experience with her? Kizuki's intent to win over Mizuho is clear, but the others, including the brainy future doctor Shin, can't resist her, either. The special bond between childhood friends seems unbreakable, but growing up sometimes means growing apart—and that's a prospect Mizuho can't bear.

What could be more explosive than love under fireworks?
