The fact he was trying so hard is what amuses you. Trying to get you to let him in on a bit of you and take you out on a date. How stupid does this guy think you are?

"I can be fun...pensive...smart-" The list went on as Eggsy bares a toothy grin. He was infatuated with you the moment he saw you on the street. And yet you only see it as some ruse to talk you out of your clothes (which it partially was, but that's for a later date).

As the rushed speech from Eggsy goes on, he continues to try and appease you. Reach and excel past whatever standards are keeping you from hearing him out on his offer.

"I can be whatever you want. Just tell me what you want and I'll be that for you."

He's eager to please and it's written in that stupidly boyish smile spreading across his lips. That smile may just be his saving grace here if you let it.
