The latest installment of the Washington Post‘sDate Lab matchmaking service adds a plot twist to the classic person-meets-person on a blind date scenario. One of the woman on this romantic first date had a boyfriend—and all parties involved thought that was great!

Kristin Richards, 31,  and Megan Caine, 34,  were set up on a date at BLT Steak on I Street. They seemed to be hitting it off, and continued to hit it off, even after Kristin revealed she had a boyfriend.

Megan: She’s in a relationship and is interested in dating people, being in a relationship and having other kinds of relationships, which is something that I appreciate and admire.

Kristin: I mean, what are the chances that that information is not problematic for a person you’re on a date with? Most of the things that I say surprise most people in the world, and she was not that taken aback.

The two women each gave the date a high ranking, and for their second date Megan invited Kristin’s boyfriend along so she could meet him.

The two of them decided to add a third for their next date at a neighborhood bar. “She invited my boyfriend so she can meet him,” Kristin says. “It was really fun to hang out with them both,” Megan says. “Kristin was still awesome and really great to be around, and [he] was also interesting and fun and engaging and attractive.” Plans for a third date are in the works.

Everyone has their own relationship and dating preferences, and open relationships are part of that. But it seems the Post may have gotten lucky on the way this one worked out: The application for Date Lab, which describes itself as a service that matches up “D.C.-area singles until we find a pair with romance potential,” doesn’t even ask applicants if they are in a relationship, or open to polyamorous relationships.

Still, all three appeared to fare pretty well with this Date Lab—and it’s good to see the Post finally took City Paper‘s advice and extended their matchmaking services to more than just heterosexual singles.
