#3 Keith Lee and Mia Yim
Another lesser-known WWE couple on the current roster is that of NXT Superstars Keith Lee and Mia Yim. While the company has heavily used the relationship of Johnny Gargano and Candice LeRae in their storylines, the same hasn't been the case with that of Lee and Yim.
Both the Superstars signed with the company in 2018 and are currently two of the biggest babyfaces on the Glack and Gold brand. Mia Yim has been a prominent part of the NXT's women's division with some consistent performances. We might even see her win the NXT Women's title in the future.
Keith Lee is destined to be a top WWE Superstar in the future as we saw the massive trust the management have shown in him recently. He was the stand-out performer in 2019's Survivor Series men's elimination match as he went on to eliminate Seth Rollins and reached the final two in the match before getting pinned by Roman Reigns.
He later appeared at the 2020 Royal Rumble and had a chilling showdown with none other than the Beast Incarnate, Brock Lesnar.
While the couple has teamed up a few times at NXT live events, we are yet to see the two of them getting involved in a storyline on-screen.
