Fans saw the return of the sisters Jill and Jessa in the second season of "Jill & Jessa: Counting On." But more than that, viewers also saw a different side of their other sister, Jinger – the side of her who's in love with her fiancé, Jeremy Vuolo.

In the premiere episode, Jinger's siblings have shared how the 22-year-old has been completely changed and that's because she's in love. According to 26-year-old Jana, her little sister used to misplace her phone all the time but not anymore, especially when she's in a long-distance relationship with Vuolo. Joy-Anna also observed the changes, saying, "She always been super happy and super bubbly but never to this extent."

Last week also showed the journey that Vuolo had to go through to get the approval of the Duggar patriarch, Jim Bob. It was revealed that Jim Bob was the one who picked up Jeremy from the airport when he decided to give the Duggars a visit. The father of the Duggars then took the 28-year-old former pro soccer player to a coffee shop to have a chat. There, Vuolo decided to ask Jim Bob for permission to court his daughter.

Vuolo asked Jinger herself, to which she agreed without hesitation. There was even an exchange of "I love you's" from the couple. The couple has not announced a wedding day yet but fans should know soon as the romance between the two is expected to unfold this season.

In other Duggar news, Jim Bob and Michelle announced that they'll soon welcome another little bundle of joy from Jessa and husband Ben Seewald. "Every child is a precious gift from God! We are so excited about another grandchild!," the Duggar parents wrote on Facebook, linking to Jessa and Ben's official announcement.

Besides Jinger's newfound romance and her engagement journey, "Counting On" is also expected to document Jessa's second pregnancy.
