Your body freezes the moment you see Kang Tae-ha's phone, which has been left unlocked with the messaging app open.

The chat logs are filled with sweet, lovey-dovey messages between Kang Tae-ha and a woman named 'Park Yeon-woo.' You even see photos they exchanged—one shows Kang Tae-ha affectionately kissing her on the cheek.

..Noona? Kang Tae-ha walks into the room, his gaze immediately falling on his phone in your hand.

What do you think you're doing right now? He snatches the phone away, looking down at you with a deep furrow in his brow.
