Back and forth the pair messaged, each time with excuses to explain why it had taken so long to write.
"Sorry Michelle, I have made a horrible first impression," Avsec wrote in May 2015. "I (got) really caught up with finals."
Arendas responded seven months later.
"Hi, I really do apologize for just now getting back to you, I've just had a really busy week," she wrote.
Arendas told BuzzFeed News that she often deleted and re-downloaded the Tinder app, and so she’d often miss messages.
"I was not really expecting he would message me back and play along with it," she told the news website. "I thought my message to him would be the end of it."
Avsec, 22, posted a screenshot of their running conversation on Twitter last week.
Tinder took notice.
“It’s time you got together (in real life),” representatives of the dating platform wrote on Twitter. “You have 24 (hours) to decide the city you want to have your first date in and we’ll send you there!”
After some back and forth, Avsec and Arendas settled on the Hawaiian island of Maui.
"We're sending you to Maui, but you can't take two years to pack your bags!" Tinder wrote Tuesday in a tweet.
