Well, you see, Ruka and him are supposed to be a couple because of Chizuru, Kazuya wanted to break up (and straight up not even date her at all) but Chizuru "admires" Ruka's straightforward feelings and insisted he should date her, If I remember correctly, before all this date thing happened Chizuru is shown asking about Ruka to Kazuya, meaning she knows they are still "dating"
Honestly that situation is so weird, and everyone has forgotten about it and the fact they are still together because of Chizuru lmao.
But, doesn't he have a girlfriend!? I was skipping to the ending because it's taking forever for just a date, I need spoilers!
