[4] Lee's senior international debut came at the Asian Championships in Hiroshima, Japan, where she helped South Korea win team bronze.

Following the Test Event, she competed at the South Korean National Championships, winning uneven bars and balance beam gold, and all-around, vault, and floor exercise silver.

She was initially named the alternate for the Olympics in Rio de Janeiro, Brazil, until her compatriot Lee Go-Im suffered an injury in training.

She placed fifty-third in the all-around, fifty-seventh on uneven bars, sixty-eighth on floor exercise, and seventieth on balance beam.

Despite winning no medals, she made worldwide headline after captured on camera taking a selfie with her North Korean counterpart, Hong Un-jong.
