Unseeded Verma lost 15-21 22-24 against his World No. 24 Korean opponent in a men's singles quarterfinal match, which lasted 42 minutes.
Verma was the lone Indian left in the fray after the big names of Indian badminton -- Ajay Jayaram, B Sai Praneeth and R M V Gurusaidutt -- lost their respective men's singles second round matches earlier to crash out of the tournament.
