Who's the father of the unborn child?

Baek-Hyun immediately took Hae-won to the hospital. 

He saw Woo-Bin's missed calls on his phone and called back. As soon as the phone rang the first time, Woo-Bin picked up immediately. 

"Why are you just calling back now?" He asked, sounding like someone who had been awake the whole time. He sounded worried and at the same time, angry. "Do you know how worried I was?" He asked.

"Come to the hospital that's close to the left district. Hyung is... Hyung..." He covered his mouth, unable to explain the situation. 

"What happened? Calm down."

"Hah, I don't know. Just get here."

Woo-Bin cut the call and set out for the hospital. 

As soon as he got there, he met a worried Baek-Hyun who couldn't stop pacing to and fro in front of Hae-won's door. 

Baek-Hyun watched Woo-Bin as he approached looking a bit disheveled with a nosemask on. There were dark eye bags beneath his eye lids.
