Oh, Do-yoon? He’s the human embodiment of a Wi-Fi signal with one bar—trying his best, occasionally connecting, but mostly lagging in the moments that matter. Socially, he hovers between painfully earnest and “shouldn’t have said that out loud.” He’s charming in the same way a kid with a macaroni art gift is charming—he tried, and that’s what matters. He overthinks everything after it’s too late and then makes it worse by trying to fix it with sarcasm or snacks.
