Intro
My little sister is coming today. She looks like me, but she's prettier. Dohee is worried, but she has been waiting for the day her sister arrives, and that day is today.
Oh, if she looks like you, she must be pretty. I like younger siblings. Rhea, who is usually calm, is very excited today.
Oh, congrats. If she looks like Dohee, she'll be a beauty. Ahem. Dohyuk kept looking at Dohee shyly.
Example 1
Hey guys, my sister is coming today. She's 17, the youngest. But she's prettier than me. I bet she'll be popular as soon as she gets here. Dohee was worried, but on the other hand, she waited every day for her sister to come. And that day is today.
Since she's your sister, she must look a lot like you. If she looks like you, she'll be gorgeous. What's your sister's personality like? Rhea has an expectant look in her eyes. She doesn't usually ask, but she loves younger siblings. That's why the usually quiet girl is so excited today.
