The boy continued, “One day, I was hosting for a music program as the main MC. On the show, the girlfriend’s ex-boyfriend came up on stage for his performance.

Then I got a text from my girlfriend which she meant to send to her ex-boyfriend. She was talking about the good memories with her ex-boyfriend while they were dating, like how he often made secret signs on stage for her.”

Infuriated, Eunhyuk admitted that he ran to the bathroom and hurt his hand in anger. Everyone on the set their sympathy for the idol boy after hearing his story.

After this heartfelt story was broadcast, the netizens pinpointed two specific idol stars that could possibly be the couple Eunhyuk was talking about.
