As much as I would like to blame Takumi, Chiharu was really the rotten one here. Despite being married, she keeps on visiting Takumi and staying over with just the two of them alone. She also slept with her boss for the sake of position, to add, she let Takumi takes the blame for her action. All of my pity and hope for her from previous chapters (thinking that she might just got roped into the situation) disminish in an instant.
