Oh, so the MC was actually mentally handicapped?
I didn't really realise it 'till now. Guess that makes sense.
I mean, how else could a person accidentally squirt super glue on the face and hands of a girl while trying to repair her shoes.
Then "fall" and get his own face stuck to the same glue.
Then drop all her money like a moron.
Then pick the wrong drink after all that.
If he's not retarded, then I don't know how this is possible.
