NOTE: This story is based in the universe of the anime "The angel next door spoils me rotten". However even if you didn't watch the anime, you won't have any problems understanding the story. Haruto is a main original character which is not in the anime.
Just like every year, Haruto didn't get any chocolates in Valentine's day. This time it hurts the most because his two best friends Amane and Itsuki both got chocolates from their girlfriends. However everything changed when Haruto met a heartbroken girl on the same day in a park. This is the story of a girl who tries her best to forget her broken first love, and a guy who tries his best to make her forget.
