Kim Sang Yeon, known professionally as Bitsaeon, is a South Korean singer, dancer and member of M.O.N.T (몬트) and B.D.U (비디유).

Before debuting, he spent several years as a trainee at FM Entertainment (FM엔터테인먼트), and the company formed the group in early 2017, even releasing the single "Sorry" in May of that year as part of their pre-debut. However, their official debut kept getting delayed until January 2019, when he finally debuted as M.O.N.T's main vocalist with their first mini-album, "Going Up".

Later that year, they became the first idol group to record an MV on the Liancourt Rocks (known in South Korea as Dokdo Island and in Japan as Takeshima) with the patriotic single "대한민국만세" ("Daehan Minguk Mansae"). In 2020, the group was re-branded as M.O.N.T. Original with the intention of creating 3 separate M.O.N.T. sub-groups of 3 members each, something that was never accomplished.

He enlisted for his mandatory military service on November 30, 2020, and was discharged on May 29, 2022. Afterwards, he appeared in a few singing survival shows, trying to increase M.O.N.T's popularity without much success.

In early 2024, he entered the singing survival show "Build Up: Vocal Boy Group Survivor", eventually being part of the winning team. As a result, he signed a 2-year contract with Stone Music Entertainment (스톤 뮤직 엔터테인먼트), becoming a member of B.D.U. He re-debuted in June 2024 with their first mini-album, "Wishpool".

He will be on hiatus with M.O.N.T while he promotes with B.D.U.
