My Stepmom's Daughter Is My Ex(2022)

My Stepmom's Daughter Is My Ex is a romantic comedy series about a high school student who thought he'd escaped his past when he started fresh at a new school—only to discover his ex-girlfriend has enrolled there too. The twist: her mother just married his father, making them stepsiblings. Now they're forced to live under the same roof, share classes, and navigate an impossible situation. Determined not to lose their rivalry, both insist on being the "older sibling" in their blended family. Beneath their hostile facade, they maintain a convincing act for their parents' sake, but the chemistry that once drew them together still crackles with tension. As they're thrown together constantly, old feelings resurface and complicate their carefully constructed boundaries. The series explores whether exes can truly become family, or if some connections are too powerful to deny.
