[SUB] Sweetness and Lightning (2016)

It's the one-year anniversary of Tsumugi's mother's death, and she and Kouhei go to the countryside to attend the funeral. On the night after they get back, Kouhei is too tired to cook, so they go to an okonomiyaki restaraunt. But Tsumugi throws a fit when she finds out it's not what she thought. Kotori offers to make her real okonomiyaki to make her feel better. This time the whole gang drops in, even Kotori's mom!
