Somebody said the Mc is canonically ace, is that true?

Just finished the whole thing. He was called ace by Bonguk n he calls himself Bi. But honestly, he was more like an aromantic. He didn't know how to fall in love with anyone, and that messed him n his life pretty bad :') he'd fit the Aroace term, but still, considering him fully "asexual" felt stretched considering how he was so interested in fuckin n getting fucked by Bonguk at one point. He's definitely an Aro, that's certain.
