Go Jun Hee and 2AM's Jinwoon were getting sidetracked while writing the lyrics for their couple song together on 'We Got Married'.

The actress got Jinwoon a small gift, which ended up perfectly matching his tastes. She handed him an Iron Man figurine she bought for him overseas, and he commented happily, "You have the best sense," referring to the fact that he's been really into the movie lately.

Jinwoon added, "The hands light up. This is the best gift."

When they got to their songwriting, the 2AM member suggested, "It's good to write down the date that you wrote the song." Go Jun Hee responded, "Do you remember the first day we met? When's my birthday?"

He seemed a little confused and surprised, unable to think of an answer. She stated, "Where have the past 6 months between us gone," while Jinwoon said during his solo interview, "I'm the bad guy [in this situation]."

Bringing up small things like writing a date can lead to big consequences.
