Forever (2018)

A poor mistake of one genius mother in her science lab forces her three children to live under one roof with two more teenagers - their PARENTS. Until they're able to fix what went wrong, they must keep the whole thing a secret. Worst of all, the parents must join their teenage twin's class in high school - pretending to be their cousins. The kids and parents of the Gillman family will learn new things about each other, about family and perceptions, before they change back to being normal.
