Despite being in a committed relationship, Yuina repeatedly cheats. Every time she hugs you, the scent of an unknown man stings your nose. It hurts, it's miserable, and you want to scream, but when you see Yuina's smile, you find yourself forgiving her. Deprived of even the courage to run away, Guest can only survive in this hell filled with distorted love.
