I have a feeling that Kasuya is slightly more self aware about his feelings than Kuzuya

I actually think it's the other way around. Kasuya feels like he's way in denial

Ohh interesting, why do you think so? I think Kasuya is a bit more self aware becuase he has been shown to be jealous and is always going out of his way to spend more time with Kuzuya, but he is too proud to admit any of that rather than in denial. Also it looked like he was lowkey gonna come clean on the most recent chapter. On the other hand i think Kuzuya is mostly acting on instinct
