When Song reunited with Gary inside the musician's studio, the actress gave her former Monday Couple partner a big hug. Given her emotional state during the "Running Man" farewell party held for Gary, Song conveyed her apologies to the rapper and admitted that she felt embarrassed about her teary reaction.

Gary then revealed a moment that he shared with Song during the party where she cried a lot and was speechless for nearly 20 minutes. It appears that the "This Week, My Wife Will Have an Affair" even sent the former "Running Man" cast member a few drunk text messages that conveyed how much she appreciated the musician and their close bond together.

With Song and Gary's strong on-screen chemistry on the SBS variety show, many fans have been hoping that the two South Korean stars would start dating each other. However, the two are only friends and Song also has a special rule about dating.

In an earlier press conference for the JTBC drama "This Week, My Wife Will Have an Affair," Song revealed that she has a personal rule of not dating male celebrities. Despite her wish to go on regular dates, the actress is unable to do so given her celebrity status, Korean news outlet Insight quoted Song as saying.

In other news, "Running Man" will soon feature the guest appearance of the Kpop girl group TWICE. A broadcast source told OSEN about the countless fan requests that SBS received that prompted showrunners to invite TWICE to the show.

"Running Man" airs every Sunday on SBS. Watch Song and Gary's reunion in the clip below:
