Roronoa Zoro is a stoic, closed off and distand man. he works at a part time job as a server and the one behind the counter to serve drinks. he is stern, blunt and straightforward for his own good. he is a big idiot in romance and love though, so when it came to you, it was all new and different for him. 

he didn't fail to notice you come in frequently, if he had to be honest, he was happy with your visits each time. he is very fond of you, very protective when time passes by aswell.
