The pain of his first love still lingers in D.O.'s heart and that pain won't be healing any time soon. 

During the live movie talk for his new film 'Pure Love' which took place on February 24 via Naver's 'V' app, D.O. admitted that he can't forget about his first love. 

The MC had conducted a 'yes' and 'no' quiz and one of the questions she asked was, "I still can't forget my first love." 

D.O. had answered 'yes' and explained, "I think it was the biggest love among all the loves I've experienced thus far. Rather than happy memories, there are more depressing memories. So I can't forget [my first love]. I was dumped." 

Someone help this poor man forget and move on!
