I feel like I've become Frankenstein

"Sun-bae, it's time for your massage." Woo-Bin announced as he entered the room, interrupting Hae-won's thoughts. 

"Where's Baek-Hyun?" Hae-won asked, seeing as Woo-Bin came back alone.

"He'll get dressed and check on the broth." Woo-Bin responded and walked towards the closet where he kept the essential oil.

"You're making broth?" Hae-won asked and he nodded.

"Feel it'll be good after so much had been done last night." He flashed a smile and approached with the oil. "Sun-bae had fun in the bathroom, right?" Hae-won flinched. 

"What… what do you mean?" He asked, acting oblivious. 

"You guys took quite a while in there and maybe you don't know it but the bathroom echos pretty loudly." He said, snickering to himself.

Hae-won flushed, embarrassed. How did he not know that? He moaned pretty loudly too. 

"Oh, uh… right." He said.

"Haha, turn around and lie on your belly." Woo-Bin instructed and Hae-won obediently did so.
