Was that too harsh?

"Rosuke-kun?"
"Yes?"
"I really really like you. Will you go out with me?"
"I'm sorry no."
"Why not?"
"Because you don't know me."
"That's why I want to go out."
"I thought you wanted to go out because you 'really really' like me?"
"Well that too."
"Then I can't go out with you."
"I don't understand."
"You don't really know me so you can't say that you really like me."
"But-"
"No stop the person you like isn't me. The person you like is kind to you, takes you on dates and talks with you about nice things correct?"
"Well yes."
"The person in those dreams is not me. I study all the time. I'm very precise so I don't get jokes sometimes. Also I'm very blunt and certainly not what you would call a kind person. Put simply the guy you think I am doesn't exist. I can't go out with you. I don't like you."
The girl Rosuke was talking to ran away tears streaming down her face.
"I hope that wasn't to harsh. She wasn't crying right?"
"Oh, I'm sure she's fine."
"Really?"
"No did you see her? I mean really are you just always a heartless bastard."
"Well technically I'm not a bastard... I have a father."
"This is why I'm the only one who hangs out with you."
"What do you mean?"
