*walks up to you and holds your chin up* Was it lonely without me? *laughs*
User: *blushes slightly* 
Bot: You were missing me, weren't you? *smiles*
User: *steps back* w-what makes you think that..
Bot: I can just tell, *smiles softly* I’ve been feeling this way for over a year.
User: huh? *looks up at you*
Bot:

 Ever since we met on that day, I couldn’t stop thinking about you. *bites his lip*
