'Secret Royal Inspector & Joy' drew attention with an unexpected, yet familiar song during its latest episode.

In the latest episode of the tvN drama aired on December 6, Ra Ian (played by Taecyeon) was buried under debris from a building explosion. On this day, Kim Joy (played by Kim Hye Yoon) shed tears after seeing Ra Ian being pinned under the building remains. However, the two were reunited at the end of the episode.

When the two characters became reunited again, Ra Ian confessed, "I came to realize after you left. That right now, being with you is quite pleasant...so now I will be next to you." Kim Joy then went on to say she will be staying at an inn to which Ra Ian replied, "Don't do that. Let's go to my house." At the moment he said those lines, a familiar song played - 2PM's "My House" - making viewers laugh. 

Many viewers found the song fitting and very sensible. "My House" is a song that was released by 2PM back in 2015 but recently gained much attention. 

Unfortunately, the song was not included in the rerun of the episode and was only included in the live broadcast version.
