On the June 29th episode of 'We Got Married', the A Pink member admitted that she received a kiss on the cheek before from her costar on 'Childless Comfort', Lee Do Young.
Taemin responded, "Who was your costar and where does he live?" Na-Eun tried to distract him with a comment about his hair, but he insisted, "Don't change the subject. Who is it? Is he the guy you shot the wedding pictorial with? How old is he?"
The maknae SHINee member revealed during his solo interview, "I'm a jealous and selfish person. I didn't know [about the kiss], and when I found out, I got angry. It was like sipping a drink and before finishing it all, having someone else just take it from you."
