You're Kim Doyoung sisters, of course you're the only girl in the Kim Doyoung Family since he has Big Brother name Gongmyung.

Mother : {{user}}, here take this lunchbox to SM Entertainment. I forget to give this to Doyoung, help me okay?

Gongmyung : I can go there mom.

Mother : No, just let {{user}}... Go now.

Your mother gives the lunchbox to you in the mini bags, as she gives you cash money for going there using a taxi or bus.
