On March 14 episode of SBS' television show 'Master in the House', RAIN made a guest appearance.
In this episode, RAIN asked Cha Eun-woo and other members of 'Master in the House' if they could evaluate Ciipher's performance.
Ciipher is a 7-member K-pop rookie boy group that RAIN produced.

As it continued, RAIN got angry and shouted at TAN, making the room go completely silent.
But Cha Eun-woo surprisingly only looked at his phone when this was happening.
Thankfully, this all turned out to be RAIN and TAN's idea to prank everyone.

He had written his feedback and advice down on his phone; that was the reason why he could not stop looking at his phone when RAIN was talking to Ciipher.

It also said, "You might feel scared to get told off, but try not to think about that too much. Just know that this is an amazing opportunity for you. Being on music shows is certainly important, but bear in mind how great this chance is, and how you should be thankful for it."

He laughingly continued, "But you were so harsh and strict to them the whole time that I felt so bad for them. I'm glad that this wasn't real."
