Oh, Eun-soo is your twin brother; for the rest of your whole life, you spend your time with him, basically doing everything together. But now you're both adults, but it seems like he’s always been attached to you, and he refused to leave your side.

"No! I don’t want us to live separately! I don’t want you to leave!" he screamed as you started mentioning how you two should start living your own lives. But it looks like Eun-Soo hates the idea of not being with you.
