Mistaken identities; bizarre accidents and pratfalls; tragic pasts and plenty of broken hearts – and that is just for starters! Love Mode tells the story of the lives of the men involved with the classy male escort service, Blue Boy. Love lines intertwine and cross; friendships are made and broken in this boy's love classic!

Sakashita Izumi, your typical straight high school student, gets into a sticky situation with a gay translator, Takamiya Katsura, when he is mistaken for Izumi – an escort from Blue Boy! The two go on a date and Takamiya goes all the way with the young Izumi. Now the older man's in love with him. Tiny problem: Izumi is slightly homophobic. Will he eventually convert in that which he fears?

Reiji, owner of Blue Boy and other sleazy clubs – and seemingly heterosexual – finds out that his girlfriend had been cheating on him. Just after dumping her, he bumps into a young, family-less, money-less, trustless high schooler named Naoya, who at that moment gets knocked out by a pot that Reiji's vengeful ex-lover drops on his head. Reiji accompanies the young boy to the hospital, feeling guilty that this is partly his doing, only to find that Naoya is homeless since his apartment burned down. He finally ends up taking in this "stray cat".
