On the upcoming episode airing this February 2, Henry's pretty little sister will be visiting Korea while vacationing from work. 'I Live Alone' has released some still cuts from the episode to tease viewers, hinting at Henry's transformation into a doting older brother. The idol does everything from picking his sister up with a sign which reads, "Welcome my girl!", to gifting her flowers, opening the door for her, doing her hair, and more.
