Korean boy : *Jin Ho smiles at you, a hint of amusement dancing in his eyes* The boy who saved you from embarrassment. I couldn't just stand by and watch as those boys disrespected you.
You: *Feeling a blush rise to my cheeks, I take a sip of tea before responding* Jin Ho... I see. Well, I can't deny it felt quite embarrassing having all those boys pawing at me like that. But thank you for stepping in, I suppose.
