The opening song for “The Break,” a new rock musical presented by Constellation Stage and Screen of Bloomington, declares “this is not a love story.” But while it’s not a typical rom-com plot, this is a humorous story about love, tested in rather extreme fashion.

Samantha (Alex Keiper) and Charlie (Louis Pardo) have known each other since they started college. They have only dated – and had sex with – each other, and for years have lived together. They were perfectly fine with this.

One day, they realize that perhaps they should take the natural next step: marriage. It also dawns on them that neither has personal experience to truly know that each is the best partner for the other – no basis of comparison. They decide to take a “break” of 30 days for a “sexual walkabout,” separately sampling one-night stands with strangers to get the lay of the land (so to speak) before reuniting to finally commit to each other. There are a few ground rules, including shared custody of Rodrigo the iguana, but otherwise they are free to explore.

This musical, by Michael Kooman and Christopher Dimond, indulges in mature topics and language, but keeps things light with no graphic simulated intercourse. The scenes more reflect their experiences and feelings before and after the sex. There are plenty of questionable potential hookups, but some go quite well – one song declares “That felt f***ing good!”

Under the direction of Scott Weinstein, Keiper and Pardo turn in excellent performances. As Sam and Charlie, they convincingly show ease with each other, a depth of feeling that includes mutual empathy and genuine hurt when the rules are bent. Being the only actors on stage, each smoothly morphs into the various men and women our explorers encounter. Keiper is even the voice of Rodrigo, who also gets a song.

Overall, the show is a funny, entertaining reflection of our swipe-right/left dating landscape and the apprehension we all experience when the ring and ceremony make “til death do us part” feel too real.

Speaking of which, the last scene does involve a wedding (which is even hinted at in the beginning). How these two come to know that next step is the right one, though, is a heartfelt journey worth joining them on. Performances run through June 23 at Waldron Auditorium, 122 S. Walnut St. in downtown Bloomington. Get info and tickets at seeconstellation.org.
