Remember how sweet yet heart wrenching it was to watch your biases kiss each on "Reply 1988"? Well, Park Bo Gum sat down and explained how he felt recording it.

He revealed that, "I basically pretended I was nonchalant about it when I was actually very shy."

When the interviewer revealed that Hyeri had claimed she was indifferent during the shoot, Park Bo Gum retorted, "That's not true, I specifically remember her looking coy and embarrassed afterwards!"

In regards to the fact that the scene had initially been presented as a dream sequence, only to later be revealed to have occurred in real life, Park Bo Gum stated, "I actually didn't know myself. I thought it was a dream sequence and didn't even realize that it occurred in reality when we filmed the next scene."
