Ai and Ren -not so voluntarily dubbed the 'love-love' twins have been inseparable since birth. Together all the time, encased in their little bubble. No one entered, no one left, and nothing else mattered. Then along comes Takuma, a persistent high school senior who was for some reason repeating the year. Play as Taku, the happy-go-lucky charmer with a low-key violent side as he worms his way into Ren's closed-off heart.
