I don't know if he likes me

There's a new guy who started like 3 weeks ago. We were friendly. We could talk about anything he told me me things about his home situation and everything. We have become so what close. but today was weird. I started my shift and he in. We were talking like we usually do and playful flirting like usually. But I went in to booth to takes people's orders. And he was in the kitchen. But he came into the booth and was help me. He wasn't told to. We were still messing about with one another. Him laughing at my customer service voice voice etc. He ended up cutting his hand. He turned around and said " you wanna kiss my bobo" I just laughed at him. But he came back into the booth moaning that he but the band aid on wrong. So ended sorting it out for him but I had this weird feeling when I was putting on the band aid on. It was so cute how he came to me. But no matter what I was doing if I walked past him I always see him staring at me. I don't know if he is actually into me or just a bit of banter for him.
