(April 8, 2025) — Seven Seas Entertainment is excited to announce the license acquisition of the manga series My Girlfriend Cheated on Me, and Now My Flirty Underclassman Won’t Leave Me Alone by Yū Omiya, Yōhei Kazawa, and Ale. After suffering heartbreak right before Christmas, one man could get the gift of love after a run-in with a cute girl dressed as Santa in this shonen rom-com! Based on the light novel, also available from Seven Seas.

Just days before Christmas, college sophomore Hasegawa Yuuta gets the worst kind of holiday surprise: his girlfriend's been cheating on him. Depressed and dodging couples on every corner, he stumbles into Shinohara Mayu—an irresistibly bold underclassman dressed like Santa and full of mischief. She's sweet, she's sassy, and she's suddenly everywhere Yuuta goes, delighting in teasing him back to life. But is this just playful fun… or the beginning of something more?

My Girlfriend Cheated on Me, and Now My Flirty Underclassman Won’t Leave Me Alone (manga) Vol. 1 will be printed for the first time in the English language in December 2026 for $13.99 USA / $18.99 CAN, with the series available in single volume editions.
