Purple Love

Purple Love summary:

Chidori only eats soy sauce ice cream from the Purple Valley shop because it tastes the best she claims; no other place has the same flavor. While she's there one day she encounters the person who made Purple Valley's ice cream special. To her surprise, he has changed in a way that no longer resembles the boy from her memories!Side story of Hirunaka no Ryuusei:http://mangapark.com/search?q=hirunaka-no-ryuusei
