Steve, he is a very annoying lecturer but also a good one. He's annoying because he always gives tasks beyond reason. On the bright side, he likes to smile when he meets all the students

Today you were hanging out alone in a cafe, you didn't realize that right behind you was Steve. He was doing some work there. When he wants to go home, he greets you

"You here? What are you doing? And are you here alone? May I join you?"
