Original: きのう何食べた？
Lawyer Shiro pours his heart into home-cooked meals for his partner, hairstylist Kenji, as they navigate life as a middle-aged gay couple in Tokyo.
Shiro is a lawyer. He loves cooking supper for himself and Kenji, a male hairdresser. But at the table tonight, things get a bit rocky for this couple.
One morning, Shiro forgets his cell phone and Kenji happens to see a suspicious-looking message from a woman. Could it be a secret lover…!?
Though Shiro's parents finally accept his relationship with Kenji, something feels off. Shiro is unable to face Kenji and express what is on his mind.
On the day of Shiro's father's surgery, Shiro hands his mother a small hand towel, but is unable to tell her the gift is actually from Kenji.
Shiro’s mom is worried about his future as he ages. He tells the usually cheerful Kenji he doesn't want to visit her but receives a stern reply.
Shiro has a lot on his plate: a bombardment of invitations from Daisaku, a new and pretty female apprentice to advise, and a jealous Kenji to placate.
Shiro and Kenji go on a double date with Daisaku and Wataru. When Shiro catches a cold the next day, Kenji tenderly looks after him.
Shiro sits with Kenji and another gay couple at a restaurant full of straight men and women. He becomes embarrassed and treats the gay couple coldly.
While Shiro is struggling to understand why he's getting so much attention from the women at a wedding, Kenji goes out with Miyake who needs to vent.
Miyake wants to remodel the salon for his wife. Kenji is concerned about Miyake's lovers, but keeps quiet. Tensions begin to rise between the two.
Shiro’s mom wants him to bring Kenji home for the New Year. Back at his own place, he suggests spending Christmas with Kenji, Daisaku and Wataru.
Kenji feels restless about meeting Shiro's family. In an unexpected turn of events, Kenji finds himself alone with Shiro's father.
