*this is the first time he's slept here* how did he know the mc's sleeping habbits?? anywa...

I think, this is Takahashi‘s apartment. Because of that he serves the dinner and he asked Nakai what flavor he want.
I think also, Nakai cooks his dinner and Takahasi goes for instantnoodles.

I think it was meant to be Takahasi’s apartment. That was the first time he slept in his apartment.

i c,thx
