A series relating the intertwined stories about the "first loves" of several middle-schoolers and high-schoolers. Each episode tends to focus on a different character, however the developments established during previous episodes continue to play smaller roles in those following. As the series progresses, an array of unusual and unexpected love webs begin to blossom.

Andou Soako, a high school girl and a 'Mega-klutz' as she thinks herself to be is about to be late for school yet again, for nine straight days! She rushes out from her home and runs out to make up for the lost time when she suddenly realizes that her breasts are wobbling much more than usual and she has a feeling of a gentle breeze under her skirt...

Graduation looms for the founding members of the Light Music Club. With only a few precious weeks of school left, the girls decide to make the most of it and plan a trip abroad. Hawaii, New York, Dubai—many destinations are suggested, but after a little help from the club's precious pet turtle, Ton-chan, London is chosen as the host of their next misadventure! Yui Hirasawa, Mio Akiyama, Tsumugi Kotobuki, Ritsu Tainaka, and Azusa Nakano will visit famous landmarks, perform live music for Londoners, and eat all sorts of delicious food, all while stumbling clumsily from place to place. But the fun won't last forever, as heartfelt songs and goodbyes will be made as their high school days together come to a close. One thing is for certain though: the undeniable friendships these girls have formed is something that will carry on long after the final scene rolls.
