Plot
Suspecting that Futaba has a man, Grandpa goes to meet her, however, she refuses to go with him and talk about it. Harumi Takeda sees this and guesses that some weird guy is pushing himself on Futaba and steps in to help her. Clearing the misunderstanding, they all go over a drink, where Grandpa and Takeda end up liking each other's company.

While going to eat with Futaba, Takeda decides to use the bathroom, but ends up meeting Grandpa. He asks Takeda to ask Futaba how's work as he doesn't want to do it himself as it would feel weird if he do it and he didn't want Futaba to hate him, but Takeda refuses. Returning to the table, they see three guys hitting on Futaba, Takeda stops ones, while Grandpa grabs and lifts the other two, scaring them away.
