Former f(x) member Sulli and Choiza have been spotted dating several times and their respective SNS accounts have been flooded by their couple photos. But, have you ever wondered how the two became a couple?

Just this week, Koreaboo answered this question that has been bugging the curiosity of the netizens. The answer was actually revealed on the episode of "Name List Reveal" last January 9 where Sulli and Choiza's couple ranked as number 5 on the celebrity couples with big age gaps. The two actually had a 14-year age gap but indeed, age doesn't matter as the two are still showing a strong relationship.

On the same show, it was revealed that Super Junior's Kim Heechul was actually the cupid of the two celebrities. When Heechul threw a party after getting discharged from the military in 2013, both Choiza and Sulli were present. It was also the same event where Choiza got Sulli's number, and as they say, the rest is history.

Although Sulli and Choiza denied the dating rumors before, the two are now more open about their relationship as evident on their SNS accounts. The two recently posted some couple updates on their respective Instagram accounts.

All Kpop wrote that the two were recently spotted at Incheon International Airport together with Gaeko and his wife for a vacation getaway. After the rumors spread like a wildfire on SNS, both Sulli and Choiza hushed them by posting a confirmation video showing the lovely couple alongside Gaeko and his adorable wife.
