In Good Doctor, episode 2, Cha Yoon Seo(played by Moon Chae Won) yelled at Park Si On(played by Joo Won) as she woke up with seeing him shirtless.
Last night, Yoon Seo got drunk and came to her old house where Si On currently lived. As she woke up with seeing him half naked, she freaked out and screamed.
Si On calmly said to her, “This is my house.” Yoon Seo yelled, “You bastard. You stay there. Don’t come near me!” Si On looked at her emotionlessly while scratching his body.
