"To our baby sister,Seohyun. It doesn't feel like you're the maknae at all. You have deep thoughts and you're more mature than us older girls and that's really good. It's good to watch you develop yourself and study hard. You take my critisim well so it amazes me *laughs*  and I'm sorry for a lot of things. I want to take this time to say sorry and I won't nag you as much. So please throw away the sweet potato peels in the trash and your banana peels too. Okay? I trust you! . Oh, And Seohyun-ah, You're getting prettier by the day  so I'm getting insecure. I wonder what your wedding would be like..."

It looks like a message from a mom to her daughter xD
