Nachuan - It means the sea takes all the rivers, but it’s also when so

It means the sea takes all the rivers, but it’s also when someone is so good-looking they could make a king lose his crown.

My neighbor said, 'You’re Nachuan, you’re so hot I can’t even eat my dinner.'

My crush said, 'You’re like Nachuan, I’m just a tiny stream trying to reach you.'

My dad said, 'You’re acting like Nachuan, you’re too good-looking for this family.'
