Second Male Lead Steals Her Heart

Synopsis

To escape an arranged marriage, I crashed at my childhood sweetheart's place. Then, in the middle of the night, something like live-stream comments popped up in front of me. The first one said, [Holy shit! What is the second male lead doing with his hand down there?] As I wondered what these words meant, a few more lines caught my attention. [Seriously? He's jerking off with just one wall between them?] [If the female lead steps out now, she'll hear his breathless, desperate moans.] I suddenly realized that Ryan in the next room was probably doing something he'd never want me to walk in on.
