Why does Byul suddenly hate Hwa?

Surely, Chin-hwa noticed from the beginning that this guy was not Kang-woo, but his emotions were a wreck when he was so drunk out of his mind and in the presence of someone else.

"Hey, why are you crying again?" He asked, frantically trying to stop his tears but they only flowed faster.

Chin-hwa wouldn't stop crying.

"Let me take this for first, you must be hot." Ji-hoo said and took off his beanie, only to discover that Chin-hwa was way more adorable without the beanie.

He looked at the beanie in surprise.

"Wait, is this a magical object or something? How was it able to hide your cuteness so well?" He asked but Chin-hwa only cried more.

"Oh, I'm sorry. Please, stop crying." He knelt in front of Chin-hwa.

"Where is Byul?" Chin-hwa asked. "I want Byul."

"Are you looking for a star?" Ji-hoo asked but Chin-hwa shook his head.

"No, my Byul." He said and Ji-hoo's eyes fell on his pouted lips.
