Henry amazed viewers with his overflowing sweetness towards his sister. However, there were moments of awkwardness between him and Whitney. Regarding this, Henry said, "I left home at the age of 18. I didn't get to spend much time with my sister so honestly, it's a bit awkward. I want to be good to her but I don't know how."

The idol treated his sister by taking her to his favorite restaurant and also took the time to introduce the 'I Live Alone' members via video call. 

Henry also went shopping with Whitney and told her to buy any and everything she wants. The bill tallied up to 936,000 KRW (861 USD). Despite the hefty bill, Henry expressed satisfaction as he revealed, "I don't often have the chance to buy things for my sister."

Watching Henry and Whitney's sweet sibling bond from the studio, fellow 'I Live Alone' members expressed amazement and commented, "They are very unrealistic siblings."
