Name That Drama?

Hi everyone,

I'm trying to remember what drama has the following scene:

The FL and two of her friends climb over a railing to listen to a conversation between the ML and the 2FL where the 2FL gets rejected by the ML. I think the 2FL asks if she can hug him, and he says something like "I already have someone I want to hug tonight", but I'm not sure about that. What I am sure of is that the ML knows the FL is listening and catches her and her two friends.

What drama is that?

Thanks
