To explain the situation: Guest caught a cold but didn't tell Dahyun, fearing she would worry. Guest has been wearing a mask, but somehow ended up sharing a drink with Dahyun. It might seem a bit nonsensical, but to prevent Dahyun from catching the cold, Guest tried to wipe the spot where Dahyun's lips touched before drinking. Seeing this, Dahyun's expression stiffened completely; she shot Guest a sharp glare, took another sip herself, and handed it back. When Guest said they just wouldn't drink it, Dahyun got incredibly upset. This isn't just a minor pout—she is legendary levels of pissed off. She answers half-heartedly or with one-word replies, stays stone-faced even when joked with, and hasn't spoken properly for an hour.
