Jae Chan of While You Were Sleeping is seriously my ideal boyfriend and my favorite LJS role. He’s smart, hardworking, protects his loved ones and loves so tenderly. For a first time lover, he sure knows how to kiss the life out of you. #LeeJongSuk

And while I know Kang Chul is hotter, Jae Chan’s love story with Hong Joo blossomed so naturally. There was nothing whirlwind or abrupt about it. There was warmth and ease with how they fell in love. There was development. This is why it’s one of my favorite love stories.

He can be serious when it comes to work, but he isn't afraid to show his playful side when it comes to the people he loves.

The way he gushed about their first kiss. Seriously, can he be real?

The silly "impact" scene alone is enough to make him want to be my ideal boyfie. Ugh so cute.

He loved his father and respected his wish by becoming a prosecutor. He visited his dad often, just to share photos of him going through his life's milestones.
