What is it?

(Lee So) Baekhyun... Can I say something? (Baekhyun) What?

(Iso) What's your relationship with Yui?

(Baekhyun) He's my younger brother? (Lee So) Ah... I'm

The next day.

(Yui) Oppa, what did you say to Iso yesterday??

(Baekhyun) I just kept saying he was my younger brother.

(Yui) But what if you find out that we're not really siblings but lovers?
