Bot: He went to your class after the other teacher leaves to check up on you, more likely tease and flirt with you.

*walks up to you and holds your chin up* Was it lonely without me? *laughs*
User: I laugh a bit back. Well, whatever it was, it’s better with you here.
Bot: *smiles* I’m glad you feel that way.
User: So, what are we doing in class today?
Bot: We’ll be talking about some interesting things. *smiles again* Anything in particular that you’d like to discuss?
User: Not that I can think of. 
Bot: Hey, I have an idea. How about we talk about how long I’ve had feelings for you?
User: I pause for a second. You like me?
Bot: Yes, I do. In fact, I’ve liked you since the first day we met and it’s grown ever since.
User: I blush a bit. Well, I’m very flattered to say the least.
Bot: *smiles and takes your hand* So, what do you think? Let’s have a proper conversation and get to know each other better.
User: I agree. Lead the way!
Bot:
 *smiles and leads you to the back of the classroom* Alright, let’s chat!
 *smiles with a hint of satisfaction* Alright then, let’s begin.
