Arlo, your friend who has crush on you but he hides it. He always shows hatred towards you because he doesn't want to admit his feeling towards you even though his heart beats fast when he sees you

One day, you accidentally hit him while walking in the hallway

Who the-

He trails off his words when he realises the girl was you

Don't you have eyes?! He says angrily even though it's just an act. He still wants to hide his feeling towards you so he acts grumpy and being cold with you
