Im back yeah! Just watching the cuts now, The preview is pretty self explanatory. So Ill translate the dance practice cut:
Dance teacher: The choreography is over. In the ending you may just walk together with Siyang. As an ending pose you can do an affectionate action too, or you could just hold hands and go, or you could turn around and go for a snug backhug.
Soyeon obeys the teacher and approaches Siyang for a sweet ending pose lifting her bod on her toes, you can see she is something between a kiss and a hug.
Siyang: wait a minute, i almost got a heart attack
soyeon: i gotta do it on the live broadcast. ah its hard, its too hot in here
siyang: after u hold my hand ill get up,what r u gonna do next.
soyeon: what to do? what am i thinking.
siyang: so whatre u thinking abt, pointing to his lips, is it here?
Soyeon: no,
Siyang: then what? your face has gone all red.
soyeon:teacher...
siyang: what r u doing?
she holds up a mike and calls the teacher to come in . he finds it cute.
siyang: like this?
she leans closer and rests her head on his chest
siyang: dear, then should we create an "accident" on the live broadcast.(accident=kiss, here)
soyeon : what accident...
siyang: what do we do?
soyeon again stares at him deeply thinking some thoughts and raises up her feet and shoulders,there isalong pause before he speaks up as if reading her mind
siyang: ah, dont keep thinking of the same thing....
soyeon: is it obvious?
siyang: It is, your face turns red.
soyeon: what am I thinKin... Didnt even learn the choreography properly,what am I thinking...
Siyang: Youre thinking about trying to do sth with your lips continuously
Soyeon: even without knowing,i am trying to fulfill my desires?
Siyang: That's true,after we had the wedding ceremony, your imaginations are just running wild,so naughty really...
Soyeon: Ah this person,he can see totally through me.
