Mariko had her world collapse when her live-in boyfriend cheated on her and the company she worked for went bankrupt. Deep down, she thought, "I'm done with men once and for all." But when she started working at a new company, her kind and popular supervisor, Sato—who treated everyone with warmth and was especially well-liked among the female staff—invited her out to dinner. For the first time in a long while, Mariko felt her heart flutter from a man's kindness. Then one day, she witnessed Sato kissing another female coworker. In love, one might experience sorrow. Yet, only when you meet someone who truly values and cherishes you for who you are, do you finally realize what real happiness feels like.
