Masaki's older brother reccommendation landed him in a part-time job at a theme park. But on his first day, a person wearing a bear costume ran up to him shouting "Maa-kun!" and hugged him tightly. Masaki has no memory of this bear (Oosawa) at all. As time passes by, Masaki gradually begins to fall for Oosawa, but the 14 year age gap and the scars left from the past put Oosawa in a difficult position.
