Nearly four months after their October wedding, Jamie Chung admits the wedding day wasn’t the nerve-wracking part of getting married to Bryan Greenberg.

But rather, the decision to leave her name behind and take on her new husband’s.

“I think I was tripping out more so when we had to turn in the marriage license after we got married because that, like, really sealed the deal,” the 32-year-old tells PEOPLE in this week’s issue. “When you go to the courthouse they ask you, ‘What do you want to do? Which name do you want to take?’ and I hadn t really thought about it until that moment and I felt so much pressure.”

Chung ultimately decided to keep her own last name, but she says the decision was tough.

“I was like, ‘Why do we have to change our names?’ I come from a generation of all women, so there s really no one to carry on the family name,” she explains. “I had to think about it and it s so weird – it’s just a weird thing to go through.”

The couple does have the option to hyphenate once they have children, which Chung says they plan to do.

The newlyweds are starring in a new romance film together – Already Tomorrow in Hong Kong – which Chung says also brought a lot of pressure.

“We read [the script] out loud and we loved it and we kind of went through the pros and cons of working together,” she explains. “We were like, pro, we get to work in a movie together, which is really rare and probably never going to happen again and we would travel to Hong Kong and southeast Asia afterwards.’ But then the cons were like, well, we have chemistry in real life, but what if it doesn t work on camera? And working long hours and then going home and working on lines and being in a relationship and sharing a hotel room, we were like, it could drive us crazy.

In the film, the couple meets in Hong Kong and falls in love, which Chung admits was a fun challenge.

“It was really important that these characters showed that excitement and that electric feeling of when you first meet someone,” she explains. “It was really hard to try and reinvent that and so because we spent so much time together, we decided to get like different hotel rooms in Hong Kong and try to spent some time apart and we tried different things to get that initial energy.”

She adds, “The tricky part was unlearning each other and try to keep those feelings organic of when we first met on screen and what not. But the dialogue kind of did it for us.”

Already Tomorrow in Hong Kong is in theaters Friday.
