Bitter Sweet

I was living in the coffee shop that I worked part-time at.. My dream is to make a living off of my paintings. The coffee shop I work at lets me display my paintings throughout the store, and one day a man who comes in regularly told me he liked my paintings, and it made me really happy.... but then he tells me he doesn't only like my paintings.. but he likes me too! To be honest, I didn't have any feelings for him, how do I let him know without hurting his feelings...? Source: MediBang
