As the business manager of the Din and Tonics and the business manager of the Radcliffe Pitches, Liston and Chou first started spending a lot of time together when they set out to plan a joint concert.
Neither of them expected the job to be as pleasant as it was.
"As a lark, I asked her to the City-Step formal as friends," Liston says.
"We didn't really expect anything of it. We had such a good time."
Many of their friends were surprised to see the two dating, because they seemed so different. She's from California, he's from Massachusetts. She was a chemistry concentrator, he history.
But the two got serious quickly. Originally, the engagement was going to be two years long. But "this spring, we cracked," Liston says, after being separated for the first summer of their relationship.
"She was in California waiting to see about medical schools, and I was at summer camp working. That was real hard," he says. "We got engaged as soon as we came out to the East Coast."
Liston and Chou are planning to get married in December.
