What would you do if you could square things with classmates from high school? Get even with the bully? Ask the most popular person for a date? Make amends to someone you wronged?

That’s part of the premise of the WB’s reality series “High School Reunion” (8 p.m. Sunday).

Seventeen people on their 10th reunion — former students at Oak Park-River Forest High School — are whisked to Maui, and are given just enough rope to entangle themselves.

Conceived by producer Mike Fleiss, on a roll with ABC’s “The Bachelor” (who also has that network’s “The Bachelorette” starting next week), “High School Reunion” cannily selects high school archetypes as participants, including the homecoming queen, the jock, the bully, the class clown, etc.

Getting those who used to go to school together to hang out for two weeks on a lush island probably didn’t take much arm-twisting (since they’re in their late 20s, the majority of them still are studly enough for revealing swimwear, a reality show staple). Still, there has to be more than people lounging on the beach.

“High School Reunion” stirs that pot with “hall passes,” fantasy dates for someone with the person of their choice. Those dates help fuel the series; those who never had a chance with someone 10 years ago can fulfill their wishes with the help of experience and, in some cases, better looks.

That’s the charm of the show. People watching will engage in role-playing — how would you react if you had a chance with someone you lusted after when you were a teenager?

There are a lot of soapy developments in the first few episodes. One of the soapiest belongs to Nicole Redmond, once the so-called “tall girl” of OP-RF. She had an unrequited crush on former playboy Dan Babato, and came to the reunion with plans to make him her “future husband.”

But Redmond, appearing a little pathetic in her initial attempts, gets a lesson in being careful what you wish for.

The series also plays off a dirty pleasure of reunions: Seeing how kind — or unkind — life has been to certain people.

Capturing the imagination is something few reality series have done lately as the genre matures. “High School Reunion” does just that, and does it almost effortlessly.
