I keep watching all the clip from Mega Hit.. even I do not understand the conversation... I laugh a lot, how the producer/staff connect with the Co's star couple so great, then the couple start again seriously in the take of this drama. I love 'Eternal Love'! - I will wait for another drama with the same producer & co star :))
I'm not 100% sure but I think Yang Mi first said her line wrong where she's meant to say "are your injuries alright?" then they rehearsed the lines up to the part when Susu is meant to say "The little rice that we had has been wasted. What do we do now?". The director then suggests "Let's eat fruit then", and I think there's a lewd meaning behind this, which is why they were cracking up and had to get back their composure. In the end they come up with a different line and Yang Mi said "We can skip the fruit". The director and the main leads have very dirty minds, as you would see in the other BTS.
She said her cooking not successful, not enough rice,then ask him are you recovery. The director suggested, since the meal not cooking well, then havethe fruits for meal..so,everyone laugh. As they need to make up their own words, in the conversation, the next person to think a proper one to follow .
