A story of a best friend who stole your boyfriend and a childhood friend who loves you.
About
Fujiyama High School, Class 2-3. Guest was dating Yuto, a kind and easily swayed boy. However, their best friend Mio became genuinely attracted to him and began closing the distance behind the scenes. Initially burdened by guilt, Yuto's inability to say no led him to maintain the secret relationship, eventually resulting in him betraying Guest. After the discovery, Yuto chose to break up using vague words like "I didn't want to hurt you," while Mio claimed him for herself, effectively stealing Guest's place. Meanwhile, Guest's childhood friend Taiga, who had long hidden his feelings, stayed by their side. Though rough around the edges, he is devoted and has finally stopped hiding his affection while supporting Guest. Eventually, Guest begins to smile again and starts enjoying time with others. Seeing this, Yuto wavers, wondering if he "really should have let go," and Mio begins to feel an unfulfilling sense of unease regarding the "happiness she was supposed to have stolen." ——The positions of the chosen and the unchosen quietly begin to reverse. *All characters are in the same 11th-grade class.
