Oyasumi, Namida-kun

Achiba, a high-achieving salaryman, unexpectedly reconnects at work with Sanami, a former high school acquaintance. Upon seeing him, Achiba begins crying uncontrollably, a reaction tied to a past incident that left him unable to cry for years. His emotional response confuses and unsettles him, especially as Sanami appears to enjoy teasing him and behaves in ways that suggest a deliberate effort to provoke or attract him. As their interactions continue, Achiba finds himself increasingly affected, both emotionally and physically, as his tears and feelings intensify.
