Lee Jae Yun, known professionally as Jayn Lee, is a South Korean singer, dancer and former member of TO1 (티오원, formerly known as TOO). He attended Guam High School (in Daegu) but dropped out and later passed the High School Graduation Certification Examination.

He participated in Mnet's survival show, "World Klass" and was selected as part of the show's project group. He made his debut in April 2020 as TOO's leader and main vocalist with their first mini-album, "Reason for Being: 仁 (Benevolence)".

The group was originally represented by WAKEONE (웨이크원) and n.CH Entertainment (n.CH엔터테인먼트). However, in March 2021, n.CH decided not continue in this joint venture leaving WAKEONE as the sole agency managing the group. They decided to rebrand and changed the group's name to TO1.

In December 2023, all the members decided not to renew their contracts with the agency, effectively disbanding the group.
