He will return

Nakashima Natsumi has a lot to say. 

Her mouth does not cooperate with her brain. 

"No, I am not." She blinks her eyes. "Why did you come inside the cave?"

"You screamed for help," Sung Soo Hwan mumbles as he strokes her cheek. He adds with a regretful tone, "I should not have sent you here."

"Wakana wasn't there," Natsumi says to him quickly as she tries to grasp her emotions. Why the hell was she worried about him? Did he notice her feelings? She doesn't have feelings. That was just… just… what the heck was that? Her sister is still missing!

"I see." Sung Soo Hwan carries her. "You did a good job."

"Yes, Sister-in-law did a good job!" Seung Won sniffles. "I am so happy for you, Elder Brother."

Sung Soo Hwan walks faster, trying hard to leave Seung Won Behind.
