Club career OB Born in Odense, Breum began his youth career with local side Ubberud IF before moving to Næsby Boldklub, both feeder clubs of OB. He joined OB's academy in 2018. On 6 March 2019, he signed his first professional contract with the club, a three-year deal. On his 18th birthday, 17 November 2021, he extended his contract until June 2026. He scored his first professional goals on 3 April 2022, netting twice in a 2–1 league win against Nordsjælland. Later that season, he appeared as a substitute in the Danish Cup final against Midtjylland, which OB lost on penalties after a 1–1 draw following extra time.

In the 2024–25 season, Breum was used primarily as an attacking midfielder after earlier appearances on the wing. On 10 January 2025, he scored a hat-trick in a 3–0 away win at Fortuna Sittard. He was named the Johan Cruyff Talent of the Month for February 2025. Later that month he sustained a foot fracture in a match against Ajax, ruling him out for an extended period.
