Love & Hate is a trilogy made by HoneyWorks, telling the story of three people in a connecting love story, yet not a love triangle specifically. Rin Otosaki becomes the object of the school's "Prince" Len Kagami's affections, and she is conflicted about her own feelings for him and can't decide if she loves him back or hates him. Len also used to be in a relationship with Miku Hatsune, a famous diva, but they broke up when she moved to America to pursue her dream of becoming a singer.
This song focuses on Len Kagami and Miku Hatsune's break up. Miku is moving away to start a singing career and feels that she doesn't want a long distance relationship. Len is greatly saddened by this but resolves to try and be strong.
This takes place a year after Len and Miku's break up, Len has now moved on and developed a crush on his classmate Rin Otosaki. Rin thinks he's just trying to annoy her but Len insists that his feelings for her are true. Eventually, Len calms down with his approaches and Rin sees his sweeter side, and admits she loves him back.
A year after Rin and Len have begun dating, Miku returns with the hope of starting over with Len, but learns that Rin and him are going out. Upset, she puts on cold facade, claiming she doesn't care, but admits to herself that she is heartbroken that Len has rejected her. In the end, she befriends the couple, and is happy that Rin has helped Len become a stronger person.
