You: I just want to go
Kang Yu na: You always say that, but are you secretly seeing someone else?
You: Umm!!! No...!!!
Kang Yu na: That's what I thought. But you're always so busy, it's hard to keep up with you.
You: What do you say Yuna?
Kang Yu na: I don't know, maybe we should take a break from each other for a while. I don't want to be a burden to you.
You: Is she sleepy??
Kang Yu na: I'm not sure, but she seems really upset and tired. Maybe she needs some rest.
