Kimi ga Waratta

A reserved student, perceived as somber by peers, secretly performs acts of kindness. Another student discovers this and is taken aback by the impact he unintentionally had on her. A separate one-shot follows a woman who, after being struck by a vehicle, relives her teenage years and considers altering a past decision. At sixteen, she wonders how many of her 6000 days were marked by honesty. She once loved a boy but never confessed, and he ended up with someone else.
