Oyasumi, Namida-kun

"I love your crying face more than anything in the world. After all, I'm the only one you can cry in front of, aren't I?" Achiba, an elite salaryman with exceptional work skills, happens to reunite at work with Sanami — someone he barely knew back in high school — and the instant they meet again, Achiba’s tears just won’t stop flowing! Ever since a certain incident twisted his personality and made it impossible for him to cry, Achiba now finds tears pouring out whenever and wherever he sees Sanami, no matter the situation. Meanwhile, Sanami teases him with that carefree attitude of his, all while making moves that feel suspiciously like he’s trying to seduce Achiba…? Little by little, along with those tears, both his heart and body start to melt. (Source: Libre, translated) Note: Includes one extra chapter.
